Description
TV RGB OUTPUTS ARE ACTIVE
TV RGB outputs are mute (Blank level)
RGB sync /DC restore source = RGB
RGB sync /DC restore source = Aux_YC or Enc_YC depending on source selection

Aux_Fnc pin = output, TV_Fnc pin = output
Aux_Fnc pin = output, TV_Fnc pin = input
Aux_Fnc pin = input, TV_Fnc pin = output
Signals will pass through from Aux_Fnc to TV_Fnc or vice versa.

The voltage applied to this pin (when set as an input) sets the state of the
two LSBs of the read register. See the note*
RGB output amplifier gain = normal
RGB output amplifiers attenuated by 10%
RGB output amplifiers attenuated by 20%
RGB output amplifiers attenuated by 30%
BLANK = ABLANK
BLANK = EBLANK
BLANK = 0V
BLANK = 4V @ IC output pin
* Function pin voltages: (I) in output mode, are defined by the two LSBs of register 2, (II) in input mode, set the
state of the two LSBs of the read register.
Digital read is not meaningful in the pass-through mode( xxxx11xx ).
** Aux_Cin is not available on the 48 QFN package option.
*** Not available in the 48 QFN package option.
