Description
The ICS650-22 is a low-cost, low-jitter, high-performance
clock synthesizer for personal video recorders (PVR) and
set-top box (STB) applications. Using analog Phase-Locked
Loop (PLL) techniques, the device accepts a 27 MHz crystal
input to produce multiple clocks for personal video recorder
applications.
