Cypress Semiconductor Corp. has announced volume production of its programmable spread-spectrum clock generator (SSCG).

"The challenge of designing high-speed digital systems today is meeting higher performance demands while effectively reducing EMI," said Mehdi Behnami, product marketing manager for Cypress's Timing Technology Division. "The CY25200ZZC significantly reduces the cost of complying with electromagnetic compliance (EMC) standards, at the same time speeding time-to-market without degrading system performance."

Wide range of spread percentages

Offering versatile programming features, multifunction outputs and control pins, the single-chip CY25200ZZC can replace alternative two-chip solutions while reducing EMI. It features flexibility, and provides a wide range of spread percentages (0.5 to 5 percent) for maximum EMI reduction. By integrating frequency synthesis and input gain block into the CY25200ZZC, the device can run effectively with any crystal or crystal oscillator input. And by using the product, Cypress customers can eliminate higher-order crystals or crystal oscillators.

The CY25200ZZC features six clock outputs and offers a wide operating output frequency range, which enables designers to program the EMI reduction from 3MHZ to 200MHz. Depending on the application, the device provides up to 20dB EMI reduction using a worst-case harmonic.

Available in a 16-pin TSSOP package with a commercial operating temperature range between 0C and 70C, the SSCG is priced at $1.35 per unit in 1,000 unit quantities.
