SI5351B-B04759-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5351B-B04759-GM is a factory preprogrammed I2C programmable clock generator from the Si5351 family. It features an internal VCXO and generates up to eight non-integer-related LVCMOS frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device operates on a core supply voltage of 2.25 V to 3.6 V and output voltages of 1.8 V, 2.5 V, or 3.3 V. It utilizes a 20-QFN (4x4 mm) package and supports spread spectrum modulation. Typical period jitter is less than 70 ps peak-to-peak.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Generates multiple independent clock frequencies using high-resolution MultiSynth fractional dividers
Integrates a highly linear VCXO for synchronous clock generation without external pullable crystals
Configurable spread spectrum modulation selectable at each output to reduce EMI
Supports glitchless frequency changes and static phase offset adjustments

Clock Generators, PLLs, Frequency Synthesizers Applications

Replacing crystals, crystal oscillators, VCXOs, and PLLs in cost-sensitive designs
Audio/video equipment and gaming consoles
Printers, scanners, and projectors
Residential gateways and networking/communication systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the B04759 suffix against system requirements. Confirm that the 20-QFN package dimensions and thermal characteristics match the PCB layout. Ensure the I2C address and control logic compatibility are validated before finalizing the design.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this variant when a fixed, factory-defined clock tree is required rather than field-programmable flexibility. The Si5351B architecture specifically addresses applications needing both free-running and synchronous clocks derived from a single reference. Verify that the required output frequencies fall within the supported range and that the 20-pin form factor fits the enclosure constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5351A/B/C-B series, which differentiates models by their reference input capabilities. The 'B' designation indicates the inclusion of an internal Voltage Controlled Crystal Oscillator (VCXO). The 'GM' suffix denotes the 20-QFN package type, while the numeric code specifies the unique factory programming parameters.
