FPGA Interfaces
The interfaces which are supported in Board-to-Board Connector3 from Kintex Ult FPGA
’s PL is explained in the following
section.
2.9.1.1
GTY High Speed Transceivers
The Kintex Ult FPGA (KU19P) supports 20 GTY transceivers through Four transceiver Quad (Bank 228, 229, 230, 231 & 232)
with line rate from 500Mbps to 32.75Gbps based on the speed grade of the FPGA. These transceivers can be used to interface to
multiple high-speed interface protocols. Each GTY transceiver quad supports two dedicated reference clock input pairs.
In Kintex Ult FPGA SOM, on board reference clock to the GTY transceiver quad is not supported. This must be fed from the
carrier board based on the peripheral standards used on GTY transceivers. This gives full flexibility to end user to select the required
peripheral standards on GTY transceivers. Also, On board termination and AC coupling capacitor are not supported on transceiver
lines and has to be taken care in the carrier board as recommend.
For more details on GTY transceiver pinouts on Board-to-Board Connector3, refer the below table.
