SI5350A-B03806-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5350A-B03806-GT is a factory-programmable CMOS clock generator housed in a 10-MSOP package with three outputs. It utilizes a PLL and MultiSynth architecture to generate frequencies from 2.5 kHz to 200 MHz with 0 ppm error using a 25 or 27 MHz crystal reference. The device supports glitchless frequency changes, configurable spread spectrum, and static phase offsets. Core and output supplies operate at 1.8 V, 2.5 V, or 3.3 V independently. Typical power consumption is 25 mA for the core, with period jitter typically below 70 ps pp.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed configuration associated with the B03806 suffix against the target design requirements. Confirm that the 10-MSOP package meets the board layout constraints. Ensure the required output frequencies fall within the supported range of 2.5 kHz to 200 MHz. Check compatibility with the system's crystal reference frequency.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed, custom frequency plan is required without I2C programming overhead. The 10-MSOP package provides three outputs suitable for simpler designs. Verify that the pin-controlled features like frequency select and spread spectrum enable meet the system's operational needs. Consider thermal performance if operating near maximum current limits.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SI5350A-B03806-GT belongs to the Si5350 family of factory-programmable clock generators. It serves as a replacement for multiple discrete crystals and oscillators. The 'B' indicates it is factory preprogrammed, while 'GT' denotes the 10-MSOP package type. This variant offers a cost-effective solution for applications requiring precise timing without user reconfiguration.

Clock Generators, PLLs, Frequency Synthesizers FAQ

Can the SI5350A-B03806-GT be reconfigured after manufacturing?

No, this part is factory-programmed. Reconfiguration requires ClockBuilder Pro software and a blank version of the device.

What is the maximum number of unique frequencies above 112.5 MHz that can be output simultaneously?

Only two unique frequencies above 112.5 MHz can be simultaneously output on any given output pair.

Does the device support spread spectrum on all outputs?

Spread spectrum can be enabled on outputs referencing PLLA. Outputs synchronized to PLLB do not support spread spectrum.
