Cirrus Logic, Inc. Clock Generation and Multiplication/Jitter Reduction Solution CS2200

A clock circuit IC, the CS2200 featuring both a clock generator and clock multiplier/jitter reduced clock frequency synthesizer (clean up), Cirrus Logic’s CS2x00 family is a strong entrant into the clock IC market. Based on an innovative hybrid analog-to-digital phase lock loop, the CS2x00 gives system designers a unique solution for solving the complex challenges of clock generation and multiplication/jitte r reduction. The members of the CS2x00 product family are differentiated by the method of control and/or a hardware mode configuration. The CS2200-CP is controlled via an I²C® / SPI™ control port and supports the full functionality of the CS2200. The CS2200-OTP is controlled in hardware mode via three mode pins. The functionality of the eight selectable modes is user defined and configured via the one-time-programmabl e feature. The CS2x00 is a growing family of products based on the CS2200 and configured by Cirrus Logic to support common system requirements. Please contact Cirrus Logic for factory configuration of the CS2x00 to support your unique requirements.
