STV223XD/224XC - FUNCTIONAL DESCRIPTION
3 FUNCTIONAL DESCRIPTION
The STV2238D is an integrated device that processes PIF, SIF, Video and Chroma signals while scanning for PAL, SECAM and NTSC standards. It includes a base band chroma delay line, Video, SVHS and audio switches. 3.1 DETAILED FEATURES 3.1.1 Power Supplies VCCIF: 5 V power supply dedicated to IF processors. VCCD: 5 V power supply dedicated to IC bus and digital parts. GNDD is the ground reference of these parts. VCC1: 8 V power supply for video switches, scanning part and the chroma decoder. GND 1 is the ground reference of all these functions. VCC2: 8 V power supply for the luminance, RGB processing parts audio switch and internal CVBS output. GND2 is the ground reference of these parts. 3.1.2 Picture Intermediate Frequency (PIF) - AGC amplifier. - PLL synchronous demodulator. Bus-controlled VCO for integrated tuning of the external LC resonator. For a 38.9 MHz VCO, the LC coil specification has to be: C = 39pF, f = 44 MHz 2% (LC not connected). For a 33.9 MHz VCO (L'), the VCO can be switched via the bus control. - Digital AFC via bus. - IF Automatic Gain Control (AGC) Negative modulation: top sync regulation, regulation of overmodulated signals (overmodulation regulation circuit enabled through bus control). Positive modulation: main regulation on white level with black level limitation. - Tuner-delayed AGC with bus control for AGC gain and threshold. When tuner AGC output is active, read register 03hex, data D7 is set to "1". - CVBS output with 2 bus-controlled amplitudes. CVBS output at 2 VPP if external sound trap is not connected (QSS mode). CVBS output at 2.3 VPP if external sound trap is connected (Intercarrier mode). 3.1.3 Sound Intermediate Frequency (SIF) and Sound Demodulators - QSS structure. - SIF Automatic Gain Control (QSS mode). - Built-in sound bandpass. - PLL FM Demodulator for 4.5, 5.5, 6.0 or 6.5 MHz carriers. The Sound Standard is selected by the MCU. The FM demodulator VCO is automatically calibrated using the chroma crystal VCO reference frequency. The FM Demodulator VCO is automatically calibrated for all sound standards independently of the chroma crystal VCO frequency, which is either 4.4 MHz or 3.5 MHz. For each sound carrier frequency, the IC sends an indication of the sound subcarrier level to the MCU so that it can select the proper standard. - The sound subcarrier level is valid when the FM Demodulation VCO is calibrated. This information can be read via the IC Bus. - Bus controls for FM de-emphasis (50 or 75 s) and FM deviation 25 or 50 kHz). - AM demodulator. - Sound demodulator output: either an AM or FM signal can be the output for the Mono chassis - Sound subcarriers for the Stereo chassis. 3.1.4 Audio Switch - One SCART switch. - Bus-controlled volume and mute. Zero-crossing function on volume control. - Automatic Volume Levelling (AVL) function can be enabled via the IC bus. Two time constants (gain increase) can be selected via the IC bus. - The AM sound can be selected on the main audio output for the Stereo chassis. 3.1.5 Surface Acoustic Wave (SAW) Filter Switch Control - SAW filter switch control pin is available in the TQFP64 package. The SAW filter switch control pin is used to select the correct SAW filter characteristics (e.g.: M/N or BGDK characteristics). In a multi-standard chassis, two output voltages are selected via the IC bus (low level voltage at 0.4 V Max., and high level voltage at 4 V Min.). 3.1.6 Video Switches - Video switch with three CVBS inputs and one CVBS output (CVBSOUT1) which may be used to drive a teletext decoder. - A second CVBS output (CVBSOUT2) is able to output recombined Y+C signals. All switches are independently controlled. - SVHS switch, Y input is combined with CVBS 3 input. CVBS/SVHS modes can be selected either by bus control (software selection), or by sensing the DC voltage on the Chroma Input pin (hardware selection). If the Chroma Input is
17/76
STV223XD/224XC - FUNCTIONAL DESCRIPTION
grounded, the CVBS mode is selected and the bus control is not active. If the DC level of the Chroma Input is higher than the SVHS threshold, then the bus control for the SVHS switch is active. Therefore, the SVHS mode can be selected by hardware using a special SVHS connector that includes a mechanical switch. In this type of application, the bus control is set to SVHS mode, and the CVBS mode is selected by grounding the Chroma Input pin. 3.2 DEFLECTION PART - Fully-integrated synchronization separator with a low pass filter, black level alignment of the CVBS input, and a 50% slicing level for the synchronized pulse amplitude. - Vertical output pulse is locked on a pulse that is twice the horizontal frequency to ensure perfect interlacing. - Auto-calibrated VCO using the chroma crystal reference. Crystal control pin X1/VAMP/ CHROUT indicates the crystal reference value on Pin XTAL1. When a 4.43 MHz crystal is connected to Pin XTAL1, the output load on Pin X1/VAMP/ CHROUT must be greater than 80 k. When a 3.58 MHz crystal is connected to Pin XTAL1, the output load must be less than 10 k. Two Phase-locked Loops (PLL): - The first PLL locks the VCO to the video line frequency, - The second PLL compensates the line transistor storage time. Three time constants for the first PLL. - [X,Y]: Line number referring to the internal line counter numbering system. The long time constant is used for normal operation. The short time constant is automatically used during the VCR search mode and frame retrace when the frame pulse is outside [258,264] and [309,314]. The very long time constant is used when there is no video recognition (very good OSD stability). Time constants in normal operation (automatic selection of time constants): - 50 Hz input signal: short time constant: [306,21], long time constant: the rest of the field. - 60 Hz input signal: short time constant: [0,16], long time constant: the rest of the field. Inhibition of the first PLL: The first PLL is inhibited from line 309 to line 4.5 (or 314) in 50 Hz mode and from line 258 to line 5.5 (or 264) in 60 Hz mode. The time constant values are chosen by means of external components. - Possibility of forcing the short time constant during the allframe via the bus. - Possibility of forcing the long time constant during the allframe via the bus. - Possibility of forcing a very long time constant during the allframe via the bus. Video identification: independent from PLL1. The video identification status is available in the output register of the IC bus decoder. Generation of burst gate pulses and line frequency signals from the first PLL to drive the Chroma and Video circuits.The burst gate pulse is also sent to the super-sandcastle generator. Frame synchronized window: - large window: [248,352] in AUTO mode, [248,284] in forced 60 Hz mode, [288,352] in forced 50 Hz mode. - narrow window: [309,314] in 50 Hz mode, [258,264] in 60 Hz mode. Field frequency selection windows: - [248,286] 60 Hz mode selection window. - [288,352] 50 Hz mode selection window. Frame blanking pulse adapted to standard: - from line 309 to line 21 in 50 Hz mode, - from line 258 to line 16 in 60 Hz mode. Long blanking mode: the end of frame blanking is line 21 both in 50 and 60 Hz modes. This mode is useful when the flyback time of the vertical output stage is longer than the 60 Hz blanking time. It is used to optimize the 50/60 Hz vertical amplifier application due to long frame blanking. Vertical output pulse duration is 10.5 lines. Horizontal output pulse: 28 s line pulse on an open collector output. Start-up circuit: the horizontal output is at high level (disabled) when VCC1 increases from 0 to 6.0 V and when VCCD has not reached 4 V. Soft mode circuit: it provides a softer operating horizontal output with a 75% duty cycle [tHIGH / (tHIGH +tLOW)]. This results in a smaller conducting time (16 s instead of 28 s). This mode is active at start-up until two frames after the VCC2 reaches 75% of the VCC1. It is also active at shutdown when the VCC1 floats between 6 V and 5.4 V. And finally, this mode is used if the VCC2 drops below 75% of the VCC1.
18/76
STV223XD/224XC - FUNCTIONAL DESCRIPTION
At shutdown, horizontal pulses are disabled when VCC1 is less than 5.4 V or when VCCD is less than 3.5 V. The horizontal output pulse may be disabled via the bus (force a high level on HOUT). Safety input on BCL Pin. When the BCL Pin is switched to ground, the horizontal output pulse is disabled and the inhibition of horizontal output pulse is maintained until V CC1 is less than 3 V (VCC1 power supply is switched off). The Safety function can be disabled via the IC bus. When register 15hex data D7 is set to "1", the Safety function is reset and no longer active. The horizontal position adjustment is controlled via the bus. Bus-controlled DC output voltage for adjusting the vertical amplitude. This voltage supply is used to adjust the slope of the vertical sawtooth generated by the external vertical booster. Bus-controlled vertical position. The high level of the vertical pulse is used to adjust the vertical position. Bus-controlled 4/3-16/9 selection. 0.2 V is the low level of the vertical pulse when 16/9 is selected and 2 V when 4/3 is selected. The Oversized Blanking function is controlled by the voltage on the FBOSD pin. When the FBOSD voltage is between the first and the second thresholds, the OSD RGB signals are selected. When the FBOSD voltage is greater than the second threshold (4 V blanking threshold), the RGB outputs are blanked during the whole field, but not during inserted cut-off lines (the cut-off loop is always active). The blanking feature, via the FBOSD input pin, enables Vertical Oversize Blanking when a 4/3 picture is displayed on a 16/9 screen in Zoom mode. The picture outside the screen is blanked by the Oversize Blanking pulse supplied by the external vertical IC (STV9306). Combined Flyback input and Super-Sandcastle output: The line blanking level is clamped at 3 V, the burst key pulse voltage is 5 V and vertical pulse voltage is 2 V. The line pulse is extracted with a 2.5 V slicing level used for RGB line blanking and PLL2 control. 3.3 FILTERS Integrated Trap Filter Q = 1.5 (f-3dB = f0 (1-1/2Q)), Center frequency: - 4.43 MHz, 3.58 MHz for PAL and NTSC. - 4.25 MHz, for SECAM (-20 dB rejection between 4.1 MHz and 4.4 MHz). The chroma trap filter is switched off in SVHS mode, or in color standard search mode (standard not identified). The trap filter can be switched off via the bus. Integrated Chroma Bandpass Q = 3.5, Center frequency: 4.43 MHz, 3.58 MHz. The Bus Control Frequency Shift is used to optimize the chroma response for the video signal from the IF stage. Integrated Bell Filter for SECAM Q = 16, Center frequency: 4.286 MHz. The Bus Control Frequency Shift is used to optimize the chroma response for the video signal from the IF stage. Integrated Luma Delay Line Bandwidth: 8 MHz. The Luma Delay Line is automatically adapted to the chroma standard. For PAL BG and applications without group delay compensation, a Luma Delay Shift of -140 ns can be selected via the IC bus. Filter Tuning All filters are tuned via a reference phase-locked loop. The PLL is based on a trap filter, a phase comparator and an internal loop filter (capacitor). The reference signal is the continuous carrier wave from the Chroma VCO (4.43 MHz or 3.58 MHz). The PLL adjusts the center frequency of the trap until it equals the reference signal.The PLL tuning voltage is used to adjust all other integrated filters. The Bell filter is fine-tuned with a second PLL during the frame retrace. The Bell filter tuning voltage is memorized on an external capacitor (BTUN Pin).

STV223XD/224XC - FUNCTIONAL DESCRIPTION
3.4 VIDEO CIRCUIT RGB Inputs The RGB (OSD) input has priority over the external RGB input. The RGB (EXT) source is matrixed into YUV signals for color and contrast adjustments. The brightness is adjusted according to the internal and external RGB and OSD RGB signals. The Contrast Control regulates both external and internal RGB signals and has a maximum attenuation of -24 dB. It also regulates the OSD RGB signal and its maximum attenuation is limited to -12 dB. The Contrast Control for RGB (OSD) input can be disabled via the bus. The brightness of the RGB (OSD) input varies according to the main brightness level. The RGB (EXT) insertion signal can be disabled or forced via the bus. A fast blanking detector on an external fast blanking input and OSD fast blanking input operate during frame retrace. The Fast Blanking detection status is sent to the IC bus read register. The OSD fast blanking input has several functions: OSD Insertion Control, RGB Output Blanking or Half Contrast Control. Half-contrast Control Pin (TQFP64) The 6 dB gain reduction will be applied to the internal YUV signals when the half-contrast function is turned ON, and the voltage of the half-contrast input exceeds the threshold (0.7 V Typ.). The Half Contrast function is also available in the SDIP56 package. The Half Contrast input is combined with the FBOSD input. Automatic Cut-off Current Loop The Cut-off Loop range is 2 V (the cut-off level of the RGB outputs is between 1.5 V and 3.5 V, 2.5 V Typ.). The cut-off current is measured sequentially during the three lines after the internal frame blanking signal (the blue cathode current is measured first, then the green and red). The Leakage cathode current is measured during frame blanking and is memorized on an internal capacitor. Cut-off pulses can be inserted after the external vertical oversize blanking signal. The Cut-off loop can be frozen via the bus. To prevent cut-off lines from being visible in 16/9 mode, cut-off pulses are not inserted when the cut-off loop is frozen. Warm-up Detector At power on, the cut-off loop is not active and high DC levels are inserted during "cut-off" lines. The Cut-off loop will be active when the cathode current reaches the warm-up detection threshold. This causes the picture to be displayed from a dark screen. The RGB outputs are blanked until cut-off current is close to the reference voltage. The manual cut-off mode can be selected via the IC bus. In this mode, the ICATH input pin is inactive and cut-off pulses are not inserted. The RGB black levels are independently controlled by three IC bus registers (8-bit resolution). The black level of each RGB output can be adjusted within a range of 2.5V typ. Beam Current Limiter DC Voltage Input (BCL) The BCL will first decrease the contrast and then the brightness when the contrast attenuation reaches -5 dB. The red, green, blue channel gain for white point adjustment takes place via the bus. The red and green DC levels for black point adjustment takes place via the bus. The PAL/SECAM matrix is provided and a specific NTSC matrix is used when demodulation angles are (0,104). Bus-controlled Contrast and Saturation The Contrast Control regulates internal RGB, external RGB and OSD RGB inputs. The maximum attenuation on internal and external RGB inputs is -24 dB and is limited to -12 dB for OSD RGB inputs. The bus-controlled saturation range is 50 dB. Bus-controlled Brightness and Sharpness The total brightness range is 60% of the black-towhite amplitude at maximum contrast. The brightness control regulates all RGB sources (internal, external and OSD). Bus-controlled Sharpness (peaking) is provided in PAL/SECAM/NTSC standards. Bus-controlled Coring function on Sharpness When the Coring-on-sharpness function is switched ON, the peaking function is not active on low amplitude signals (below 10 IRE). The Black Stretch circuit can be disabled via the bus. Two modes are provided, one to be used when the video signal is transmitted with a set-up (7.5IRE set-up in NTSC), the other to be used when the video signal is transmitted without a setup (PAL/SECAM). The bus-controlled Blue Screen feature is used to insert a blue background on the screen when no video is available. The RGB OSD can be displayed when the blue screen is active. The APR (Automatic RGB Peak Regulation) function is used to take advantage of the total RGB output range. APR circuits detect the peak level of the RGB outputs (before OSD insertion) and regulate the RGB gain (contrast) so that signals above the APR threshold are limited. For example, at maximum drive and contrast levels with the APR function switched OFF, the 100 IRE input signal gives 3 V(B/W) to the RGB outputs. With APR ON and the APR threshold at 70 IRE, the 70 IRE input signal gives 3 V (B/W) at RGB outputs. For input

STV223XD/224XC - FUNCTIONAL DESCRIPTION
signals above 70 IRE, the APR will decrease the RGB gain so that amplitude at the RGB output is always 3 V (B/W). The APR gain control voltage is memorized on an external capacitor where the gain decrease is very fast and the gain increase is very slow (several frames). The APR function can be enabled or disabled via the IC bus. 3.5 CHROMA CIRCUIT PAL/SECAM/NTSC Decoders SVHS Chroma input; bus-controlled SVHS mode. - 30 dB ACC range. - Integrated chroma base band delay line and ON/ OFF bus control. - Automatic standard identification, with possibility of forcing the standard via the bus. - 3-crystal application capability for the South American market: The first crystal on Pin XTAL1 (3.5X MHz only), he second crystal on Pin XTAL2 (3.5X MHz only), and the third crystal on Pin XTAL3/BTUN (3.5X MHz only, used for PAL/NTSC application only).

Data transfers follow the usual IC format: after the start condition (S), a 7-bit slave address is sent, followed by an eight-bit which is a data direction bit (W). An 8-bit sub-address is sent to select a register, followed by an 8-bit data word to be included in the register. The IC's IC bus decoder permits the automatic incrementation mode in write mode. The circuit operates up to clock frequencies of 400 kHz.
