ICS650-22
PVR and STB Clock Source
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.

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.
