The AMD UltraScale+™ and AMD Versal™ adaptive SoC GTY supports continuous data rate from 1.2 Gbps to 32.75 Gbps. AMD Versal™ GTY page has few differences when compared to previous device families.

In Versal devices, hard IP block selection is dissociated from GT page to Hard IP Blocks pages. Hard IPs should be configured on Hard IP Blocks page in Versal adaptive SoC.

GTY

The Versal adaptive SoC GTY supports continuous data rate from 1.2 Gbps to 32.75 Gbps. Versal GTY page has few differences when compared to previous device families.

The following Versal device clock sources are different:

LCPLL
LC-tank based VCO for low jitter, supports maximum data rates.
RPLL
Ring-oscillator based, slightly lower power, lower data rates.
Note: It is recommended to use Add GTY interface or Manage IP to enter a GTY configuration for a desired protocol, so that all columns are correctly specified. Versal devices include the following changes to the GTY configuration.

GTYP

GTYP available in Versal adaptice SoC devices. GTYP is a superset of GTY in every way, including IP and pin compatibility. It is an upgraded version of GTY that supports PCIe® Gen5. For more information on GTYP, see Versal Adaptive SoC GTY and GTYP Transceivers Architecture Manual (AM002).

GTM

GTM is a high speed serial transceiver available for Versal adaptive SoC and a few Virtex UltraScale+ devices and it supports PAM4 and NRZ signaling.

Versal adaptive SoC GTM supports non-continuous data rates between 9.5 Gbps to 116 Gbps. For more information, see Versal Adaptive SoC GTM Transceivers Architecture Manual (AM017).

Virtex UltraScale+ supports highest data rate of 58 Gbps and lowest data rate supported is 9.8 Gbps. For more information on GTM, see Virtex UltraScale+ FPGAs GTM Transceivers User Guide (UG581) Virtex UltraScale+ (Registration required).

GTH

The GTH transceivers are available in UltraScale+ devices. GTH is power-efficient transceivers, supporting line rates from 500 Mbps to 16.375 Gbps. For more information, refer to UltraScale Architecture GTH Transceivers User Guide (UG576).
