Overview

The Si5351A-B02075-GT is an I2C-programmable any-frequency CMOS clock generator capable of generating up to 200MHz on each of its three outputs. It replaces crystals, crystal oscillators, and buffers with a single IC, offering a highly flexible timing solution with 0 ppm synthesis error. This specific variant comes in a compact 10-MSOP package and operates from a supply voltage range of 1.71V to 3.6V.

Why Choose This Part

This IC eliminates the need for multiple expensive custom crystals by using an internal PLL to synthesize nearly any frequency from 8 kHz to 200 MHz. It features excellent frequency accuracy with 0 ppm error and a wide operating temperature range of -40C to 85C, making it reliable for industrial applications.

Applications

SDR and RF Synthesis
Generating precise local oscillator frequencies for software-defined radios and amateur radio equipment.
Microcontroller Clocking
Providing multiple synchronous or independent clock signals for MCUs, FPGAs, and SoCs from a single crystal.
Consumer Electronics
Consolidating timing components in printers, scanners, and digital cameras to reduce PCB footprint.
Network Switches
Supplying reference clocks for Ethernet and communication hardware requiring low jitter performance.

Getting Started

To evaluate this part, use the Skyworks ClockBuilder Pro software to generate configuration registers for the I2C interface. For rapid prototyping, many engineers use Adafruit or SparkFun breakout boards which are compatible with Arduino and Raspberry Pi libraries. Ensure proper decoupling on the VDD pins and keep clock traces short to minimize EMI.
