Clock Generator IC 350MHz 1 24-VFQFN Exposed Pad
NRND1,230 in stock

Overview

The CDCE6214RGET is a high-performance, ultra-low power clock generator designed for cost-sensitive and power-conscious designs. It features a flexible fractional-N PLL and four programmable output drivers that support multiple signaling standards like LVDS, LP-HCSL, and LVCMOS at frequencies up to 350MHz.

Why Choose This Part

The device offers exceptional power efficiency, consuming as little as 65mA for all four outputs and providing a power-down sleep mode of 2800uA. It includes an integrated EEPROM with two configuration pages, allowing for in-situ programming and 'always-on' operation without an external MCU at startup.

Applications

Embedded Computing
Generates precise reference clocks for small-form-factor processors and FPGAs in industrial and consumer hardware.
Network Interface Cards
Provides stable clocking for Ethernet controllers and storage interfaces requiring low jitter and multiple frequency domains.
Portable Instrumentation
Optimized for battery-powered devices using its 23mA single-channel mode and integrated EEPROM for standalone operation.

Getting Started

Engineers can configure the device via its I2C-compatible interface and utilize the four GPIO pins for control functions like frequency margining or DCO mode. Evaluation of the silicon is typically performed using TI's Tic Pro software for register configuration and the CDCE6214EVM evaluation module.
