SERDES Bypass DDR Differential Signaling Transmitter
Operation
The
output circuitry to transmit high-speed serial data. The DDR output
circuitry consists of a pair of shift registers and a multiplexer. The shift
registers capture the parallel data on the clock’s rising edge (generated by
the PLL), and a multiplexer transmits the data in sync with the clock.

of the data. However, other combinations are possible.
