Virtex-4/-5 - What is the minimum frequency for a PMCD clock input?


What is the minimum frequency for clock inputs to a PMCD?


There is no restriction on the minimum frequency of Virtex-4 FPGA PMCD clock inputs. This is documented in the Virtex-4 FPGA Data Sheet.
If you use the Virtex-5 FPGA PLL in PMCD legacy mode, there is a minimum input frequency specification of 1 MHz. This is mentioned in the Virtex-5 FPGA Data Sheet.
