Features
Delta-Sigma Fractional-N Frequency Synthesis
General Description
The CS2200-CP is an extremely versatile system clocking device that utilizes a programmable phase lock loop. The CS2200-CP is based on an analog PLL architecture comprised of a Delta-Sigma Fractional-N Frequency Synthesizer. This architecture allows for frequency synthesis and clock generation from a stable reference clock. The CS2200-CP supports both IC and SPI for full software control. The CS2200-CP is available in a 10-pin MSOP package in Commercial (-10 °C to +70 °C) grade. Customer development kits are also available for device evaluation. Please see “Ordering Information” on page 25 for complete details.
