ICS650-22
PRV AND STB CLOCK SOURCE
Description
Features
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.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS650-22. These ratings, which are
standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these
or any other conditions above those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical
parameters are guaranteed only over the recommended operating temperature range.
