ICS661 Datasheet | Renesas

PRECISION AUDIO CLOCK SOURCE Description The ICS661 provides synchronous clock generation for audio sampling clock rates derived from an MPEG stream, or can be used as a standalone clock source with a 27 MHz crystal. The device uses the latest PLL technology to provide excellent phase noise and long term jitter performance for superior synchronization and S/N ratio. Please contact IDT 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 - Pb (lead) free package, Ro HS pliant - Clock or crystal input - Low phase noise - Low jitter - Exact (0 ppm) multiplication ratios - Reference clock output available - Support for 256, 384, 512, and 768 times sampling rate Block Diagram VDD (P2) VDD (P3) VDDO VDDR X2 X1/REFIN SELIN S3:0 4 Crystal Oscillator GND (P13) PLL Clock Synthesis GND (P6) GND (P5) IDT™ / ICS™ PRECISION AUDIO CLOCK SOURCE REV F 051310 ICS661 PRECISION AUDIO CLOCK SOURCE CLOCK SYNTHESIZER Pin Assignment X1/REFIN VDD VDD S0 GND GND S3 S2 1 2 3 4 5 6 7...
