PLL timing chip offers spread spectrum for reduced EMI

San Jose, Calif.— Cypress Semiconductor Corp. introduced the latest member of its PREMIS (Peak Reducing EMI Solutions ) family of spread-spectrum timing products.

According to Cypress, the CY25400 is the industry's first 4-PLL (phase-locked loop) timing device with two spread-spectrum PLLs to reduce electro-magnetic emissions (EMI). The CY25400 is designed to cut costs by eliminating shielding, ferrite beads and chokes often used to address EMI issues.

The CY25400 offers two-wire I²C programming that allows manufacturers to dynamically adjust EMI reduction variables to determine optimum system configuration.

The CY25400 meets critical timing performance, voltage and power requirements for digital entertainment systems, handheld applications and consumer electronics systems, including multifunction printers, scanners, HDTV, STB, DVD-R, hard disk drives, handsets and portable games.

Pricing: Between $2.49 and $1.49, depending on quantities.

Availability: Samples of the CY25400 are available now, and full production is expected in May 2007.
