The transceivers of Xilinx XC7A200T-1FBG676C are low-power gigabit transceivers that have higher performance with a capability of 6.6 Gb/s up to 28.05 Gb/s. The transceiver’s low power mode is enabling chip-to-chip interface optimization. It has decision feedback and receiver linear equalization along with post and pre-emphasis for advanced transmission for applications that are backplane or long-reach.
The transmitter of Xilinx XC7A200T-1FBG676C is essentially a parallel to serial converter that has conversion capability in the ratio of 80, 64, 40, 32, 20, and 16. The transmitter is also supporting 160 bits of data widths additionally for allowing the designers to manage trade-off of the width of the data-path for margin of timing when higher performance designs are considered. These outputs of the transmitter are driving the board of the PC through a unity channel differential output signal. The output clock of the transmitter is divided into serial data clocks that could be utilized for registering parallel data that comes from its internal logic.
