Advance Product Information
Features
General Description
The CS2300-03 is an extremely versatile system clock-
ing 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 synchroniza-
tion clock with frequencies as low as 23 kHz. The
CS2300-03 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.
1x, 4x, 128x, and 256x Clock Multiplier with Internal LCO
