ANALOG INPUT MUXING
The ADV7183B has an integrated analog muxing section that
allows more than one source of video signal to be connected to
the decoder.
140H
Figure 6 outlines the overall structure of the input
muxing provided in the ADV7183B.
As seen in
141H
Figure 6, the analog input muxes can be controlled
by functional registers (INSEL) or manually. 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.
Control via an I
2
C manual override (ADC_sw_man_en,
ADC0_sw, and ADC1_sw, ADC2_sw) is provided for
applications with special requirements (for example, number/
combinations of signals) that would not be served by the pre-
assigned input connections. This is referred to as manual input
muxing.
Refer to
142H
Figure 7 for an overview of the two methods of
controlling the ADV7183B’s input muxing.
ADI Recommended Input Muxing
A maximum of 12 CVBS inputs can be connected and decoded
by the ADV7183B. As seen in
143H
Figure 5, this means the sources
will have to be connected to adjacent pins on the IC. This calls
for a careful design of the PCB layout, such as ground shielding
between all signals routed through tracks that are physically
close together.
INSEL[3:0] Input Selection, Address 0x00[3:0]
The INSEL bits allow the user to select an input channel as well
as the input format. Depending on the PCB connections, only a
subset of the INSEL modes is valid. The INSEL[3:0] not only
switches the analog input muxing, it also configures the
standard definition processor core to process CVBS (Comp),
S-Video (Y/C), or component (YPbPr) format.
