CDCS502PW

CDCS502PW Description

The CDCS502PW from Texas Instruments is a high-performance Spread Spectrum Clock Driver designed to reduce electromagnetic interference (EMI) in sensitive electronic systems. Operating within a 3V to 3.6V supply range, this IC delivers LVCMOS output signals with a maximum frequency of 108MHz, making it suitable for applications requiring precise clock distribution with minimized noise. The device features a 1:1 input-to-output ratio, accepts crystal input, and integrates a multiplier (no divider) to enhance signal integrity. Packaged in an 8-pin TSSOP and rated for surface-mount assembly, the CDCS502PW is RoHS3 compliant and adheres to REACH environmental standards, ensuring reliability in industrial and commercial environments.

CDCS502PW Features
