ICS661 Features
• • • • • • • •
Packaged in 16-pin TSSOP Available in Pb (lead) fere package Clock or crystal input Low phase noise Low jitter Exact (0 ppm) multiplication ratios Reference clock output available Support for 256, 384, 512, and 768 times sampling rate
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.
