Overview

The CS2600-CNR is a highly integrated clock synthesizer and multiplier from Cirrus Logic designed for low-jitter clock generation. It features an internal oscillator and automatic rate control, operating from a wide supply voltage range of 1.71V to 3.5V. This 16-pin QFN device is engineered to provide precise clock synchronization and multiplication without requiring external analog loop-filter components.

Why Choose This Part

The CS2600-CNR eliminates the need for external analog loop filters, significantly reducing board space and BOM complexity. Its ultra-low power consumption of 4mA makes it suitable for power-sensitive applications, while its support for both I2C and SPI provides flexible integration with various host controllers.

Applications

Digital Audio Systems
Generating high-precision master clocks for audio ADCs, DACs, and DSPs in consumer electronics.
Video Processing Equipment
Providing synchronized pixel clocks and timing references for video capture and display systems.
System Clock Distribution
Multiplier and jitter cleaner for recovering clean clock signals in embedded systems with noisy references.

Getting Started

To evaluate this device, engineers typically use a breakout for the 16-pin QFN package or the manufacturer evaluation board. Integration involves configuring the internal registers via I2C or SPI to set the desired multiplication ratios and output frequencies. The device supports both hardware control modes for fixed configurations and software control for dynamic frequency adjustment.
