optical black clamp control pulse input (active HIGH for TDA8786, active LOW for TDA8786A)
pre-blanking control pulse input; if PBK is HIGH (LOW) the signal is replaced by the optical
black level for TDA8786 (TDA8786A)
analog output of the additional 8-bit control DAC (controlled via the serial interface)
CDS amplifier output (fixed gain = +6 dB)
analog ground 1
analog supply voltage 1
AGC and soft clipper amplifier signal output
optical black clamp and pre-blanking block signal input (from AGCOUT via a capacitor)
optical black clamp and pre-blanking block signal output
ADC analog signal input (from PBOUT or AGCOUT via a capacitor)
clamp control input for ADC analog input signal clamp (active HIGH for TDA8786 and active
LOW for TDA8786A)
ADC input clamp reference voltage (normally connected to pin VRB or DACOUT)
DAC output for ADC clamp level
analog ground 2
analog supply voltage 2
ADC reference voltage (BOTTOM) code 0
ADC reference voltage (TOP) code 1023
decoupling 1 (decoupled to ground via a capacitor)
CDS offset storage
serial data input for the 4 control DACs (9-bit DAC for AGC gain, 4-bit DAC for soft clipper;
additional 8-bit DAC for OFD output voltage; 10-bit DAC for ADC clamp level and the stand-by
mode per block; see Table 1)
serial clock input for the control DACs and their serial interface; see Table 1
enable input for the serial interface shift register (active when SEN = logic 0); see Table 1
stand-by control pin (active HIGH); all the output bits are logic 0 when stand-by is enabled
