General Description

The CS2100-OTP is an extremely versatile system clocking device that utilizes a programmable phase lock loop. The CS2100-OTP is based on a hybrid analogdigital 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 50 Hz. The CS2100-OTP has many configuration options which are set once prior to runtime. At runtime there are three hardware configuration pins available for mode and feature selection.
