GTY, GTYP, and GTM are serial transceivers used for serial data transmission in Versal® ACAP.
In Versal devices, hard IP block selection is dissociated from GT tab to Hard_Blocks tabs. Hard IPs should be configured on Hard_Blocks tab in Versal ACAP.
The Versal ACAP GTY supports continuous data rate from 1.2 Gb/s to 32.75 Gb/s. Versal GTY tab has few differences when compared to previous device families.
The following Versal device clock sources are different:
- LC-tank based VCO for low jitter, supports maximum data rates
- Ring-oscillator based, slightly lower power, lower data ratesNote: 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 is a superset of GTY in every way, including IP and pin compatibility. It is an upgraded version of GTY which supports PCIe® Gen5. For more information on GTYP, see Versal ACAP GTY and GTYP Transceivers Architecture Manual (AM002).
GTM is a high performance transceiver that supports PAM4 and NRZ modulations. Versal ACAP GTM supports non-continuous data rates between 9.5 Gb/s to 116 Gb/s. For more information, see Versal ACAP GTM Transceivers Architecture Manual (AM017).
