General Description

The CS2300-03 is an extremely versatile system clocking device that utilizes a programmable phase lock loop. The CS2300-03 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 with frequencies as low as 23 kHz. The CS2300-03 is a CS2300-OTP device that has been preconfigured at the factory. There are three hardware configuration pins available for mode and feature selection.
