Overview

The 650-41 is a spread spectrum clock synthesizer intended for video projector applications. It generates 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. For the 50 MHz output, the modulation rate is 50 kHz. In addition to the EMI optimized clock signal, the device generates a 48 MHz clock for USB.
  • 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)
  • Guarantees +85°C operational condition
  • 25 MHz crystal or reference clock input
  • Zero (0) ppm frequency error on all output clocks
  • Advanced, low-power CMOS process
  • Industrial temperature range
