Overview

SPREAD SPECTRUM CLOCK SYNTHESIZER DATASHEET ICS650-44 Description The ICS650-44 is a spread spectrum clock synthesizer intended for video projector and digital TV applications.
It generates three copies of an EMI optimized 50 MHz clock signal (EMI peak reduction of 7 to 14 dB on 3rd through 19th harmonics) through the use of Spread Spectrum techniques from a 25 MHz crystal or clock input.
The modulation rate is 50 kHz.
Features • Packaged in 16-pin TSSOP (173 mil) • Supply voltages: VDD = 3.
3 V, VDDO = 2.
5 V • Peak-to-peak jitter: ±125 ps typ • Output duty cycle 45/55% (worst case) • 25 MHz crystal or reference clock input • Zero (0) ppm frequency error on all output clocks • Advanced, low-power CMOS process • Industrial temperature range (-40 to +85°C) • Pb (lead) free package Block Diagram 25 MHz crystal or clock input X1/CLKIN X2 External capacitors are required with a crystal input.
