uPP Rx channel clock source

I would like to know which one of the clock pins on the uPP interface (above) is connected to the CLOCK Pin on figure 33-7 (below),

and how can I change it to be VPIF_CLKIN0 (pin 32)?

    The EVM schematic label the channel A and B receive pins as UPP_CH1_CLK and UPP_CH0_CLK, respectively.  Please note that channel 0 corresponds to B and channel 1 corresponds to A, contrary to what you might expect.  This is a known issue with the EVM schematic.

    It is not possible to use any other pins (such as the VPIF clock pins) to drive the uPP receive clocks.

    Hope this helps.
