Hello Pushpa,
Assuming that the rise time is around 10% of the time period, the critical
length for this signal will be roughly around 3 inches. But with proper
termination and solid reference it should be possible to meet the quality of
the signal with 12 inches of length.

Regards,
Naren

Hello All,
Is  106.25MHz clock form the LVCMOS buffer output can be routed up to 12
inches length and still meets the signal quality?.
Thanks and Regards
Pushpa
