Overview

The SI5351A-B15671-GTR is an I2C programmable clock generator capable of replacing crystals, crystal oscillators, and PLLs in cost-sensitive applications. It features a triple-output architecture that can generate independent frequencies up to 200MHz with 0 ppm synthesis error.

Why Choose This Part

This device offers high flexibility by generating up to three unique frequencies from 8 kHz to 200 MHz while consuming only 20mA during active operation. Its integrated VCXO and spread spectrum capabilities help engineers manage EMI and reduce system jitter in sensitive timing circuits.

Applications

SDR Frequency Synthesis
Used as a stable local oscillator in software-defined radio projects requiring precise tuning.
Microcontroller Clock Distribution
Provides multiple synchronized or independent clock signals to multiple ICs from a single crystal reference.
Network Switches and Routers
Generates high-speed LVCMOS clocks for data processing and Ethernet PHYs.
Consumer Electronics
Replaces multiple bulky oscillators in handheld devices to save PCB real estate and BOM cost.
