The 650-44 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
