PI49FCT3807
3.3V Fast CMOS Clock Driver
Description
Pericom Semiconductor’s PI49FCT3807 is a 3.3V 1-to-10 clock
driver. This low skew clock driver features one input and ten outputs
fanout. The large fanout from a single input line reduced loading
on input clock. TTL level outputs reduce noise levels on the part.
Typical applications are clock and signal distributon
