Overview

The CDCE913QPWRQ1 is an automotive-qualified, low-noise PLL-based clock synthesizer designed for generating high-precision clock signals up to 230MHz. It features an integrated EEPROM for non-volatile configuration and supports spread-spectrum clocking to significantly reduce electromagnetic interference (EMI) in sensitive electronic systems. The device operates across a flexible voltage range and is functional safety-capable for demanding automotive and industrial applications.

Why Choose This Part

The integrated EEPROM allows for in-system programmability and standalone operation without an external MCU at startup. Its internal PLL loop filter minimizes component count, while the 50ps typical period jitter ensures high signal integrity for high-speed data transmission.

Applications

Automotive Infotainment and ADAS
Provides precise timing for video processing, camera systems, and navigation units while meeting AEC-Q100 standards.
EMI-Sensitive Communication
Utilizes programmable spread-spectrum modulation to lower peak radiated noise in Ethernet, WLAN, and Bluetooth modules.
Processor Reference Clocks
Generates 0-PPM accurate clock signals required by TI DaVinci, OMAP, and DSP platforms.
Industrial Safety Systems
Serves as a functional safety-capable clock source for critical control loops and sensors.
