com CS2100-CP Fractional-N Clock Multiplier General Description The CS2100-CP is an extremely versatile system clocking device that utilizes a programmable phase lock loop.
The CS2100-CP is based on a hybrid analog-digital PLL architecture comprised of a unique combination of a Delta-Sigma Fractional-N Frequency Synthesizer and a Digital PLL.
This architecture allows for generation of a low-jitter clock relative to an external noisy synchronization clock at frequencies as low as 50 Hz.
The CS2100-CP supports both I²C and SPI for full software control.
The CS2100-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 32 for complete details.
