transceiver 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 GXBL1. The tx_clkout[4] signal also drives the transmitter data
and control logic of all 16 transmitter channels in the FPGA fabric. Only one global
clock resource is used by the tx_clkout[4] signal with this clocking scheme.
