ICS660 Digital Video Clock Source Description The ICS660 provides clock generation and conversion for clock rates commonly needed in digital video equipment, including rates for MPEG, NTSC, PAL, and HDTV. The ICS660 uses the latest PLL technology to provide excellent phase noise and long term jitter performance for superior synchronization and S/N ratio. For audio sampling clocks generated from 27 MHz, use the ICS661. 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. Features • Packaged in 16-pin TSSOP • Available in Pb-free packaging • Clock or crystal input • Low phase noise • Low jitter • Exact (0 ppm) multiplication ratios • Power-down control • Reference clock output available Block Diagram X2 X1/REFIN SELIN S3:0 4 VDD (P2) Crystal Oscillator VDD (P3) VDDO VDDR REF GND (P13) PLL Clock Synthesis GND (P6) GND (P5) CLK MDS 660 E 1 Revision 040104 Integrated Circuit Systems, Inc. ● 525 Race Street, San Jose, CA 95126 ● tel (408) 297-1201 ● www.icst.com 1 page ICS660 Digital Video Clock Source AC Electrical Characteristics Unless stated otherwise, VDD = 3.3 V ±10%, Ambient Temperature -40 to +85° C Parameter Symbol Conditions Min.
