Description

The IMISG509 is a spectrum spread clock generator specially designed for personal computers, laser printers and other digital systems. IMISG509 uses a patented concept to generate popular clock frequencies that are intentionally broadbanded to reduce electromagnetic interference. The radiated emissions,associated with either the clock, harmonics or any signals derived from the clock, nominally reduced by 10 dB and could significantly reduce the cost of complying with the regulatory requirements.

PRCLK IMISG509 is the broadbanded output and can be programmed by the PRCLK Frequency Selection Table on Page 2. A single, low cost external crystal is required as reference frequency for the synthesizer.The output modulation function of IMISG509 can be disabled when the SSON pin is high.
