Debuting as the latest member of the PREMIS family of spread-spectrum timing devices, the CY25400 assumes position as the industry’s first 4-PLL timing device with two spread-spectrum PLLs to reduce EMI. The device saves costs by eliminating shielding, ferrite beads, and chokes. It also offers two-wire I2C programming that allows users to dynamically adjust EMI reduction variables for real-time determination of optimum system configuration. Essentially, the spread spectrum feature can be turned on or off and tweaked during the design process. Other features include nine selectable frequency outputs from 3 MHz to 166 MHz and four voltage output options of 3.3V, 3V, 2.5V, and 1.8V. Available in 24-pin QFN (4 mm x 4 mm), 16-pin QFN (3 mm x 3 mm), and 8-pin SOIC packages, prices range from $1.49 to $2.49 each depending on quantity. Full production is expected in May.
