Ultra-fast serial data transmission between devices on the same PCB over backplanes and across even longer distances is becoming increasingly important for scaling to 100 Gb/s and 400 Gb/s line cards. Specialized dedicated on-chip circuitry and differential I/O capable of coping with the signal integrity issues are required at these high data rates. There are three types of transceivers: GTH, GTY, and PS-GTR. All transceivers are arranged in groups of four, known as a transceiver Quad. Each serial transceiver is a combined transmitter and receiver. GTH and GTY Quads are PL peripherals and PS-GTR is a PS peripheral.
GTH serial gigabit transceivers are available in the CG and EG grade Zynq UltraScale+ devices except where noted in the Zynq UltraScale+ MPSoC Product Overview (DS891) [Ref 1]. The GTH transceivers are power efficient, supporting line rates from 500 Mb/s to 16.375 Gb/s.
The GTY transceivers are power efficient, supporting line rates from 500 Mb/s to 30.5 Gb/s in UltraScale FPGAs, and 32.75 Gb/s in UltraScale+ FPGAs.
The GTH and GTY transceivers are configured using the PS configuration wizard (PCW) available in the Vivado® Integrated Design Environment (IDE).
