Description

Pericom Semiconductor’s PI49FCT807T and PI49FCT2807T clock

drivers feature one input and ten outputs. The large fanout from a

single input line reduces loading on input clock. TTL level outputs

reduce noise levels on the part. Typical applications are clock and

signal distribution.

The PI49FCT2807T also features a 25-ohm on-chip resistor for

lower noise.
