Description
The PI6C4911505 is a high performance fanout buffer device-
which supports up to 1.5GHz frequency. The device has 2 select-
able clock inputs that can accept most differential clock sources.
This device is ideal for systems that need to distribute low jitter
clock signals to multiple destinations.
Applications
ÎÎNetworking systems including switches and Routers
ÎÎHigh frequency backplane based computing and telecom
platforms
