REV D 111804

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 IDT if you have a requirement for an input

and output frequency not included here - we can rapidly

modify this product to meet special requirements.
