Specifications

Stresses above the ratings listed below can cause permanent damage to the ICS651-03. 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.

Description

The ICS651-03 is a low cost frequency generator designed to support voice-over-internet protocol (VOIP) applications. Using analog/digital Phase-Locked Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal input to produce four output clocks supporting DSP,video encoder, and memory functions. To form acomplete VOIP clocking solution use the ICS651-02 companion device.
 
The ICS651-03 also has a power down feature that tri-states the clock outputs and turns off the PLL when the PDTS pin is taken low.
