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