ICST ICS650R-22LFT Pvr and stb clock source Datasheet

ICS650-22
PVR 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 ICS 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.
