CS2300-CP is a Fractional-N Clock Multiplier with Internal LCO from Cirrus Logic. It supports I²C and SPI control, and can generate a low jitter clock in the frequency range of 50Hz to 30MHz.
The CS2300-CP is a fractional‑N clock multiplier with an internal LC oscillator, offering low‑jitter clock generation from noisy references as low as 50 Hz up to 30 MHz. It supports both I²C and SPI control interfaces and is supplied in a 10‑pin MSOP package for commercial‑grade applications.
Key features include a 6 – 75 MHz PLL output, programmable frequency ratios, auxiliary output options, and minimal board space without an external analog loop‑filter. The datasheet details electrical characteristics, pin assignments, register maps, and typical connection diagrams for system integration.
