DATA BITS D9 to D0
OFDOUT output control (D7 to D0).
Soft clipper control. Only the 4 LSBs (D3 to D0) are used. Bits D9 to D4 should be set to
logic 0.
AGC gain control (D8 to D0).
Partial standby controls for power consumption optimization. Only the 4 LSBs (D3 to D0)
are used. Bits D9 to D4 should be set to logic 0:
D0 = 1: CDS + AGC + soft clipper block in standby; ICCA + ICCD = 48 mA
D1 = 1: optical black clamp + blanking block in standby; ICCA + ICCD = 92 mA
D2 = 1: OFD DAC in standby; ICCA + ICCD = 98 mA
D3 = 1: 6 dB amplifier (output on AMPOUT pin) in standby; ICCA + ICCD = 98.5 mA.
Clamp reference DAC (D9 to D0).
Note
1. At the end of each programming sequence (usually during the video vertical blanking), the soft clipper register must
be reloaded (for example if the soft clipper is not used, code 15 must be entered in the soft clipper register at the end
of each TDA8786(A) programming sequence).
