blocks. The tx_coreclk ports of all 16 transmitter channels are connected together
and driven by the tx_clkout[4] signal from channel 0 in transceiver block GXBR1. The
tx_clkout[4] signal also drives the transmitter data and control logic of all 16
transmitter channels in the FPGA fabric. With this clocking scheme, only one global
clock resource is used by the tx_clkout[4] signal.
