ICS661

Precision Audio Clock Source

Description

The ICS661 provides synchronous clock generation for

audio sampling clock rates derived from an MPEG

stream, or can be used as a standalone clock source

with a 27 MHz crystal. The device uses the latest PLL

technology to provide excellent phase noise and long

term jitter performance for superior synchronization

and S/N ratio.

Please contact ICS if you have a requirement for an

input and output frequency not included here - we can

rapidly modify this product to meet special

requirements.
