Figure 6. Internal Pin Connections
The ADV7188 has an integrated analog muxing section that
allows connecting more than one source of video signal to the
decoder. Figure 6 outlines the overall structure of the input
muxing provided in ADV7188.
As can be seen in Figure 6, the analog input muxes can be
controlled in two ways:
By functional registers (INSEL). Using INSEL[3:0]
simplifies the setup of the muxes, and minimizes crosstalk
between channels by pre-assigning the input channels. This
is referred to as ADI recommended input muxing.
By an I
2
C manual override (ADC_SW_MAN_EN,
ADC0_SW, ADC1_SW, ADC2_SW, and ADC3_SW). This
is provided for applications with special requirements, such
as number/combinations of signals, which would not be
served by the pre-assigned input connections. This is
referred to as manual input muxing.
Refer to Figure 7 for an overview of the two methods of
controlling input muxing.
