Virtex-5 LXT/SXT/FXT FPGA Prototype Platform
UG229 (v3.0.1) May 21, 2008
Detailed Description
R
22. GTP/GTX Transceiver Clocks to SMA
GTP/GTX Transceiver Clock Inputs
The Virtex-5 FPGA prototype platform provides a high-speed differential clock input used
to clock the input and output serial data from the GTP/GTX transceivers.
Table 14
shows
GTP/GTX transceiver clocks and their corresponding FPGA pins. The GTP/GTX
transceivers are looped back and are not connected to test points or SMA connectors. See
the
Virtex-5 FPGA RocketIO GTP Transceiver User Guide
[Ref 4]
and the
Virtex-5 FPGA
RocketIO GTX Transceiver User Guide
[Ref 5]
for more information on GTP/GTX transceiver
operation.
