Overview

The Si5351A-B15671-GT is an I2C programmable clock generator that uses a dual PLL architecture to synthesize up to three independent frequencies from 8 kHz to 200 MHz. This specific variant is factory pre-programmed for quick integration while still allowing for field-updates via the serial interface. It effectively replaces multiple crystals and oscillators in space-constrained designs, significantly reducing PCB footprint.

Why Choose This Part

This device eliminates the need for multiple discrete timing components by offering sub-100 ps jitter and high frequency flexibility within a compact 10-MSOP package. It operates efficiently with a typical run current of 20mA across three outputs and supports a wide supply range of 1.71V to 3.6V.

Applications

Embedded System Master Clock
Providing synchronized clock signals to microcontrollers, FPGAs, and peripherals from a single reference.
Networking Equipment
Generating precision timings for Ethernet switches and routers requiring LVCMOS or HCSL outputs.
SDR and RF Synthesizers
Acting as a local oscillator for software-defined radio applications where precise frequency control is required.

Getting Started

To evaluate this part, use the Skyworks Solutions ClockBuilder Pro software to customize frequency configurations and generate the necessary I2C register maps. Hardware prototyping is best performed with the Si5351A-B-EVB evaluation board, which provides accessible headers for the I2C interface and SMA connectors for clock output analysis.
