The Versal ACAP GTY supports continuous data rate from 1.2 Gb/s to 32.75 Gb/s. Versal GTY sheet 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
Recommended: 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:
| Source | UltraScale+ Device | Versal Device |
|---|---|---|
| LC PLL | QPLL (shared to 4 channels) | LCPLL (shared to 2 channels) |
| Ring PLL | CPLL | RPLL |
| Ethernet MAC | CMAC | MRMAC |
| Debug | Eyescan | Not currently supported |
