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.
