Spread Spectrum Clock Synthesizer

Description

The ICS650-41 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.

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)

• 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
