SI5351B-B02073-GM
Overview
The SI5351B-B02073-GM is an I2C programmable CMOS clock generator capable of synthesizing up to 8 unique frequencies with 0 ppm error. This B-variant includes an integrated highly linear Voltage Controlled Crystal Oscillator (VCXO) for applications requiring frequency synchronization or clock recovery. It operates from a standard 25 MHz or 27 MHz crystal and provides individual supply pins for level translation between 1.8V and 3.3V logic.
Why Choose This Part
The device eliminates the need for multiple expensive crystals by replacing them with a single low-cost 25 or 27 MHz crystal. Its excellent PSRR reduces the need for complex power supply filtering while maintaining low period jitter of 70 ps typical. Precise frequency synthesis allows for exact output frequencies with zero ppm synthesis error across all eight outputs.
Applications
Getting Started
Configuration is performed via the I2C interface using Skyworks ClockBuilder Pro software to generate register maps. Engineers should ensure proper thermal grounding of the 20-QFN exposed pad and follow recommended layout practices for high-speed CMOS clock traces. Evaluation can be expedited using the Si5351-B-EVB development kit.
