data sheet tda6170x semiconductor group 5 21.7.99 7 circuit description 7.1 general the sound intermediate frequencies contained in the baseband of a demodulated fm satellite signal can lie between 5 and 9.9 mhz. this band of frequencies is applied rough ?ltered to the high-pass input of the con- verter mixer. the purpose of this mixer is to convert the different sound ifs in the baseband to ?xed output frequencies (e.g. 10.7 / 10.72 mhz). these frequencies are then fed by external ?lters to the three sound if inputs. the vco of the mixer can be continuously tuned between 29 and 40 mhz in 20 khz increments with crystal accuracy by means of a pll circuit. the settings of the programmable divider and switching of the if mux and de-emphasis networks and volume control are done by the i 2 c-bus. pin 5 (cas) offers two switchable chip addresses to enable parallel operation of two devices. all pins are guarded against electrostatic discharge. scl and sda include special protective structures to permit continued bus operation when the device is switched off. 7.2 pll description the vco signal is applied to the pll input. it passes through a programmable divider (n=1024 to 2047) and then compared with a reference frequency (f ref = 20 khz in a digital frequency / phase detector. this fre- quency is derived from a 4 mhz crystal oscillator whose signal is divided by 200. the phase detector has a charge pump push-pull current output. if the negative edge of the divided vco sig- nal appears before the negative edge of the reference signal, the current source i+ will pulse for the duration of the phase difference. in the reverse case it is the current sink i-. if both signals are in phase, the output has a high impedance and the pll is locked. the current pulses are ?ltered by means of an integrator. the pump current can be switched between two values (1 and 5) by software with a control bit 5i. this permits a change in the control response during and after lock-in state. 7.3 fast i 2 c-bus interface information is exchanged between the processor and the sound if device on an fast asynchronous bidirec- tional data bus. the timing for this comes from the processor (input scl), while pin sda functions as an i/o depending on the direction of the data (open collector; external pull-up resistor). the bus will work with clock frequencies up to 400 khz. the data from the processor goes to an i 2 c-bus controller and are put into registers (latches 0 to x) according to their function. when the bus is not busy, both lines are in the marking state (sda, scl are high). each tel- egram begins with the start condition: sda goes low while scl remains high. all further exchanges of infor- mation occur when scl is low and are read by the controller with the positive clock edge. if sda goes high while the clock is high, the i 2 c-bus interface recognizes this as a stop condition and thus the end of the tele- gram. for what follows, refer to the table of logic assignments below. all telegrams are transferred byte for byte, followed by a ninth clock pulse during which the controller pulls the sda line to low (i.e. acknowledge condition). the ?rst byte consists of seven address bits with which the proc- essor selects the pll from among several other peripheral devices (chip select). the eighth bit is always low. the ?rst bit of the ?rst or third data byte in the data part of the telegram determines whether a divider ratio or control information for the if or audio part will follow. in every case the ?rst byte must be followed by a byte of the same data type (or stop condition). when the supply voltage is applied, a power-on reset circuit prevents the pll from pulling the sda line to low and thus blocking the bus.

data sheet tda6170x semiconductor group 7 21.7.99 7.6 expander description the demodulated and level controlled audio signals are fed via low-pass ?lters to the inputs of two identical expander circuits. the if3 audio signal is also applied in parallel via different de-emphasis networks to the input of the audio switch for broadband mono reception. the expander circuits have the reverse characteris- tics of the audio compressor of the tv station. a 3 bit pre volume control (control byte 3: pvl2...pvl0 and pvr2...pvr0) for each audio channel enables a correct adjustment of the expander characteristics and allows the possibility to align to the right level for both broadband and smallband sound if reception. 7.7 af switch and volume control the input signals of the af switch can be derived from the external audio input pair. however, these signals can also be derived from either the different de-emphasis networks or from both expanders. the selection of the output signals from if1, if2 or if3 is done by using the i 2 c-bus interface. the switches are followed by a volume control section with buffered outputs ch1 and ch2. in case of small-band reception the demodulated signals of if1 and if2 are processed in both expanders and fed to the switches. so it is possible to select one of each or both in the audio switches for both af outputs ch1 and ch2. in the case of broad-band audio transmission with 50 m s, 75 m s or j17 pre-emphasis the if3 input is active and with the audio switch the demodulated audio signals are selected after the three de-emphasis networks and fed to both af outputs in mono mode. the 3 bit volume control (control byte 2: vl2...vl0 and vr2...vr0) in front of each af output enables the same audio level for different fm deviations of several satellite transponders.
