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 a complete VOIP clocking solution use the ICS651-02 companion device.
