Virtex-5 - What is the maximum CLK input frequency of the BUFR?

Description

What is the maximum CLK input frequency of the BUFR?

Solution

The maximum BUFR input frequency is the same as the maximum BUFIO frequency, which can be found in the device data sheet.

Speed Grade Max BUFIO CLKSpeed
-3 710 MHz
-2 710 MHz
-1 644 MHz

This means that a BUFR can be driven at up to 710 MHz (-3) and can output up to 300 MHz (-3) in order to meet the BUFR maximum frequency limitation.
