Tools and Software


Featuring both a clock generator and clock multiplier/jitter reduced clock frequency synthesizer (clean up), Cirrus Logic’s CS2000 is a strong entrant into the clocking IC market. Based on a unique hybrid analog-to-digital phase lock loop, the CS2000 gives system designers a unique solution for solving the complex challenges of clock generation and multiplication/jitter reduction.

The members of the CS2000 product family are differentiated by the method of control and/or a hardware mode configuration. The CS2000-CP is controlled via an I²C® / SPI™ control port and supports the full functionality of the CS2000. The CS2000-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-programmable feature.

The CS2xxx is a growing family of products based on the CS2000-OTP and configured by Cirrus Logic to support common system requirements. Please contact Cirrus Logic for factory configuration of the CS2000-OTP to support your unique requirements.


  • High-performance analog/digital phase locked loop
  • Clock multiplier/jitter reduction
    • Generates a low-jitter 6 – 75 MHz output clock from a jittery or intermittent 50 Hz to 30 MHz clock source
  • Clock generation/frequency synthesis
    • Generates a low-jitter 6 – 75 MHz clock relative to 8 – 75 MHz reference clock
  • Highly accurate PLL multiplication factor
    • Less than 1 PPM error
  • Flexible control options
    • One-time-programmable configuration for hardware mode
    • I²C® / SPI™ control port
  • Configurable auxiliary output
    • Buffered reference clock
    • PLL Lock indication
    • Second PLL output
    • Buffered version of CLK_IN
  • Flexible sourcing of reference clock
    • External oscillator or clock source
