DATASHEET
ICS662-03
Description
www.datasheet4u.com
The ICS662-03 provides synchronous clock generation for
audio sampling clock rates derived from an HDTV stream.
The device uses the latest PLL technology to provide
superior phase noise and long term jitter performance. The
device also supports a 27 MHz output clock for video
MPEG applications from an HDTV reference clock.
Please contact ICS if you have a requirement for an input
and output frequency not included here.
Features
Packaged in 8-pin SOIC
Available in Pb (lead) free package
HDTV clock input
Low phase noise
Exact (0 ppm) multiplication ratios
Support for 256 and 384 times sampling rate
Supports 27 MHz output for video (MPEG)
