DATASHEET DIGITAL VIDEO CLOCK SOURCE ICS664-03 Description Features The ICS664-03 provides clock generation and conversion Packaged in 16-pin TSSOP for clock rates commonly needed in HDTV digital video Pb (lead) free package, RoHS compliant equipment. The ICS664-03 uses the latest PLL technology Clock or crystal input provides flexibility to provide excellent phase noise and long term jitter Low phase noise supports enhanced SNR performance for superior synchronization and S/N ratio. Lowest jitter in class at 100 ps The ICS664-03 is suitable for Digital Video STB and DTV Exact (0 ppm) multiplication ratios applications. For Transmitter application use ICS664-01 or Power-down mode lowers power consumption ICS664-02. Improved phase noise over ICS660 For audio sampling clocks generated from 27 MHz, use the Provides High definition Video clocks for 720p, 1080i and ICS661. 1080p YUV standards Please contact IDT if you have a requirement for an input and output frequency not included in this document. IDT can rapidly modify this product to meet special requirements.
