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 four mux sections can be
controlled by the reserved control signal buses ADC0_SW[3:0]/
ADC1_SW[3:0]/ADC2_SW[3:0]/ADC3_SW[3:0].
Configuration to format follow-on blocks in correct format.
