Pin Descriptions
The SRC has two interfaces: an input port and an output port.
describes the six inputs and two outputs for the IP (input port) and OP
(output port).

SRU Programming
The SRU (signal routing unit) needs to be programmed in order to con-
nect the SRCs to the output pins or any other peripherals. For normal
operation, the data, clock, and frame sync signals need to be routed as
shown in Table
