General Description

The CS2300-02 is an extremely versatile system clock-

ing device that utilizes a programmable phase lock loop.

The CS2300-02 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 synchroniza-

tion clock with frequencies as low as 750 kHz. The

CS2300-02 is a CS2300-OTP device that has been pre-

configured at the factory. There are three hardware con-

figuration pins available for mode and feature selection.
