The Versal adaptive SoC GTY/GTYP transceivers provide the greatest performance and integration at 7 nm, including serial I/O bandwidth and logic capacity. As the industry's high-end FPGA at the 7 nm process node, this product family is ideal for applications including 400G networking, large-scale ASIC prototyping, and emulation.

The GTY/GTYP transceivers in the Versal architecture are power-efficient transceivers, supporting line rates from 1.25 Gb/s to 32.75 Gb/s. The GTY/GTYP transceivers are highly configurable and tightly integrated with the programmable logic resources of the Versal architecture. The following table summarizes the features by functional group that support a wide variety of applications.
