Fanout Buffers are able to create multiple copies of input signal at their output and distribute them among several loads while achieving fast rise/fall time and low jitter. Input and output interfaces are CML and output voltage swing can be adjusted externally.

What is the need of clock buffers?

Clock buffer is typically used to fan out clock signal and isolate the source from the loads.

How does a clock buffer work?

Clock buffers are fairly straight-forward ICs for distributing multiple copies of a clock to multiple ICs with the same frequency requirements. A buffer's reference clock can be from a clock generator, an XO or a clock already present. Clock buffers scale from 2 outputs to more than 10 outputs.
