Overview

The CDCEL913PWR is a programmable 1-PLL clock synthesizer designed for high-performance systems requiring low-voltage operation. It can generate up to three system clocks from a single input frequency, supporting an output range up to 230MHz with a supply voltage between 1.7V and 1.9V.

Why Choose This Part

This IC offers in-system programmability via I2C and integrated EEPROM, allowing for on-the-fly frequency adjustments without hardware changes. The inclusion of a built-in loop filter and oscillator reduces the total bill-of-materials and saves PCB area in 14-TSSOP designs.

Applications

Embedded System Clocking
Generating multiple synchronized clock frequencies for microcontrollers, FPGAs, and ASICs from a single crystal or LVCMOS source.
EMI Reduction
Utilizing integrated spread-spectrum clocking (SSC) to minimize electromagnetic interference in sensitive digital designs.
Battery-Powered Electronics
Leveraging the low 1.8V core voltage and 30uA sleep current for power-constrained mobile or portable devices.

Getting Started

Configuration is managed through the I2C interface, where users can define PLL multipliers and dividers; Texas Instruments provides the ClockPro software tool to simplify register bit generation. Engineers should ensure the 1.8V supply is well-decoupled and follow standard high-speed layout practices for the LVCMOS outputs to maintain signal integrity up to 230MHz.

Also Consider

CDCE913PWR TITexas Instruments - Offers similar 3-output PLL functionality but operates at a higher 2.5V to 3.3V supply range for legacy system compatibility.
