GENERAL DESCRIPTION
The ADV7181C is a high quality, single-chip, multiformat video decoder and graphics digitizer. This multiformat decoder supports the conversion of PAL, NTSC, and SECAM standards in the form of composite or S-Video into a digital ITU-R BT.656 format. The ADV7181C also supports the decoding of a component RGB/YPrPb video signal into a digital YCrCb or RGB DDR pixel output stream. The support for component video includes standards such as 525i, 625i, 525p, 625p, 720p, 1080i, and many other HD and SMPTE standards. Graphics digitization is also supported by the ADV7181C; it is capable of digitizing RGB graphics signals from VGA to SXGA rates and converting them into a digital DDR RGB or YCrCb pixel output stream. SCART and overlay functionality are enabled by the ability of the ADV7181C to process simultaneously CVBS and standard definition RGB signals. The mixing of these signals is controlled by the fast blank pin. The ADV7181C contains two main processing sections. The first section is the standard definition processor (SDP), which processes all PAL, NTSC, and SECAM signal types. The second section is the component processor (CP), which processes YPrPb and RGB component formats, including RGB graphics.
APPLICATIONS

PACKAGE THERMAL PERFORMANCE
To reduce power consumption when using the part the user is advised to turn off any unused ADCs. It is imperative that the recommended scripts be used for the following high current modes: SCART, 720p, 1080i, and all RGB graphic standards. Using the recommended scripts ensures correct thermal performance. These scripts are available from a local FAE. The junction temperature must always stay below the maximum junction temperature (TJ MAX) of 125C. Using the following equation, calculate the junction temperature: TJ = TA MAX + (JA x WMAX) where: TA MAX = 85C. JA = 45.5C/W. WMAX = ((AVDD x IAVDD) + (DVDD x IDVDD) + (DVDDIO x IDVDDIO) + (PVDD x IPVDD)).

ADV7181C DETAILED DESCRIPTION
ANALOG FRONT END
The ADV7181C analog front end comprises four 10-bit ADCs that digitize the analog video signal before applying it to the SDP or CP. The analog front end uses differential channels to each ADC to ensure high performance in a mixed-signal application. The front end also includes a 6-channel input mux that enables multiple video signals to be applied to the ADV7181C. Current and voltage clamps are positioned in front of each ADC to ensure that the video signal remains within the range of the converter. Fine clamping of the video signals is performed downstream by digital fine clamping in either the CP or SDP. Optional antialiasing filters are positioned in front of each ADC. These filters can be used to band-limit standard definition video signals, removing spurious out-of-band noise. The ADCs are configured to run in 4x oversampling mode when decoding composite and S-Video inputs; 2x oversampling is performed for component 525i, 625i, 525p, and 625p sources. All other video standards are 1x oversampled. Oversampling the video signals reduces the cost and complexity of external antialiasing filters with the benefit of an increased signal-tonoise ratio (SNR). The ADV7181C can support simultaneous processing of CVBS and RGB standard definition signals to enable SCART compatibility and overlay functionality. A combination of CVBS and RGB inputs can be mixed and output under the control of the I2C registers and the fast blank pin. such as VCRs, noisy sources from tuner outputs, VCD players, and camcorders. The SDP also contains a chroma transient improvement (CTI) processor. This processor increases the edge rate on chroma transitions, resulting in a sharper video image. The SDP can process a variety of VBI data services, such as teletext, closed captioning (CC), wide screen signaling (WSS), video programming system (VPS), vertical interval time codes (VITC), copy generation management system (CGMS), GemStar 1x/2x, and extended data service (XDS). The ADV7181C SDP section has a Macrovision 7.1 detection circuit that allows it to detect Type I, Type II, and Type III protection levels. The decoder is also fully robust to all Macrovision signal inputs.
COMPONENT PROCESSOR (CP)
The CP section is capable of decoding/digitizing a wide range of component video formats in any color space. Component video standards supported by the CP are 525i, 625i, 525p, 625p, 720p, 1080i, graphics up to SXGA at 60 Hz, and many other standards. The CP section of the ADV7181C contains an AGC block. When no embedded synchronization is present, the video gain can be set manually. The AGC section is followed by a digital clamp circuit that ensures the video signal is clamped to the correct blanking level. Automatic adjustments within the CP include gain (contrast) and offset (brightness); manual adjustment controls are also supported. A fixed mode graphics RGB to component output is available. A color space conversion matrix is placed between the analog front end and the CP section. This enables YPrPb-to-DDR RGB and RGB-to-YCrCb conversions. Many other standards of color space can be implemented using the color space converter. The output section of the CP is highly flexible. It can be configured in SDR mode with one data packet per clock cycle or in a DDR mode where data is presented on the rising and falling edges of the clock. In SDR mode, a 20-bit 4:2:2 is possible. In these modes, HS/CS, VS, and FIELD/DE (where applicable) timing reference signals are provided. In DDR mode, the ADV7181C can be configured in an 8-bit 4:2:2 YCrCb or 12-bit 4:4:4 RGB pixel output interface with corresponding timing signals. The CP section contains circuitry to enable the detection of Macrovision encoded YPrPb signals for 525i, 625i, 525p, and 625p. It is designed to be fully robust when decoding these types of signals. VBI extraction of component data is performed by the CP section of the ADV7181C for interlaced, progressive, and high definition scanning rates. The data extracted can be read back over the I2C interface.
STANDARD DEFINITION PROCESSOR (SDP)
The SDP section is capable of decoding a large selection of baseband video signals in composite S-Video and YUV formats. The video standards supported by the SDP include PAL B/D/I/G/H, PAL60, PAL M, PAL N, NTSC M/J, NTSC 4.43, and SECAM B/D/G/K/L. The ADV7181C automatically detects the video standard and processes it accordingly. The SDP has a 5-line super adaptive 2D comb filter that gives superior chrominance and luminance separation when decoding a composite video signal. This highly adaptive filter automatically adjusts its processing mode according to video standards and signal quality with no user intervention required. The SDP has an IF filter block that compensates for attenuation in the high frequency luma spectrum due to the tuner SAW filter. The SDP has specific luminance and chrominance parameter control for brightness, contrast, saturation, and hue. The ADV7181C implements a patented Adaptive-Digital-LineLength-Tracking (ADLLT) algorithm to track varying video line lengths from sources such as a VCR. ADLLT enables the ADV7181C to track and decode poor quality video sources

The analog input muxes of the ADV7181C must be controlled directly. This is referred to as manual input muxing. The manual muxing is activated by setting the ADC_SWITCH_MAN bit (see Table 9). It affects only the analog switches in front of the ADCs. INSEL, SDM_SEL, PRIM_MODE, and VID_STD still have to be set so that the follow-on blocks process the video data in the correct format. Not every input pin can be routed to any ADC. There are restrictions in the channel routing imposed by the analog signal routing inside the IC. See Table 9 for an overview of the routing capabilities inside the chip. The three mux sections can be controlled by the reserved control signal buses ADC0_SW[3:0]/ ADC1_SW[3:0]/ADC2_SW[3:0].
