DATASHEET DIGITAL VIDEO CLOCK SOURCE ICS664-01 Description Features The ICS664-01 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 ICS664-01 uses the latest PLL technology Clock or crystal input provides flexibility to provide excellent phase noise and long term jitter performance for superior synchronization and S/N ratio. Low phase noise supports enhanced SNR Lowest jitter in class at 100 ps For audio sampling clocks generated from 27 MHz, use the ICS661. Exact (0 ppm) multiplication ratios Please contact IDT if you have a requirement for an input Power-down mode lowers power consumption and output frequency not included in this document. IDT Improved phase noise over ICS660 can rapidly modify this product to meet special Supports SMTE 292M HD-SDI standard for HDTV requirements. broadcast Block Diagram VDD (P2) VDD (P3) VDDO VDD (P14) X2 Crystal Oscillator X1/REFIN SELIN PLL Clock CLK Synthesis S3:0 4 GND (P6) GND (P5) GND (P13) IDT DIGITAL VIDEO CLOCK SOURCE 1 ICS664-01 REV E 051310ICS664-01 DIGITAL VIDEO CLOCK SOURCE CLOCK SYNTHESIZER Pin Assignment Output Clock Selection Table Input Output S3 S2 S1 S0 Frequency Frequency X1/REFIN 1 16 X2 (MHz) (MHz) VDD 2 15 N/C 0000 Power down VDD 3 14 VDD 0001 Pass thru Input Freq 0010 27 74.25 S0 4 13 GND 0011 27 74.175824 GND 5 12 SELIN 0100 13.5 74.25 0101 13.5 74.175824 GND 6 11 VDDO 0110 RESERVED RESERVED S3 7 10 S1 0111 RESERVED RESERVED S2 8 9 CLK 1000 74.25 54 1001 74.175824 54 1010 RESERVED RESERVED 16-pin TSSOP 1011 RESERVED RESERVED 1100 54 74.25 1101 54 74.175824 1110 54 13.5 1111 27 13.5 Pin Descriptions Pin Pin Pin Pin Description Number Name Type 1 X1/REFIN Input Connect this pin to a crystal or clock input 2 VDD Power Power supply for crystal oscillator. 3 VDD Power Power supply for PLL. 4 S0 Input Output frequency selection.
