Analog ports

Here is how the 16 analog ports of a module could be connected to our crosspoint switches. The ports are carried from the faceplate to the backplane through the FPC1 connector. From there, they are routed to pins X0 through X15 of the two AD75019 crosspoint switches, which will be daisy-chained to provide switching between 16 X inputs and 32 Y outputs (the crosspoint bus’ 32 endpoints). According to this design, pin Xn on CS1 (Crosspoint Switch 1) is directly connected to pin Xn on CS2 (Crosspoint Switch 2).

Note: The part used for FPC1 is likely to change in the future.
