SI5350C-B03275-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B03275-GT is a factory-programmable CMOS clock generator featuring a dual PLL and MultiSynth architecture. It generates up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device supports glitchless frequency changes, configurable spread spectrum, and static phase offsets. It operates on core and output supply voltages of 1.8 V, 2.5 V, or 3.3 V. The GT suffix indicates a tube package containing three LVCMOS outputs in a 10-MSOP form factor.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory-programmed configuration associated with the B03275 suffix against the official datasheet or ClockBuilder Pro export. Confirm that the 10-MSOP tube packaging aligns with assembly requirements. Ensure the crystal reference matches the programmed 25 MHz or 27 MHz specification.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when a fixed-frequency solution is required without I2C programming overhead. The Si5350C replaces multiple crystals and oscillators. Verify that the pin-controlled features meet system needs, as I2C configuration is not available for pre-programmed variants.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of clock generators. The 'C' variant supports both crystal and external clock inputs. The 'GT' designation specifies the 10-MSOP package with three outputs, distinguishing it from the 16-QFN (four outputs) and 20-QFN (eight outputs) options.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements include other Si5350C variants with different output counts or packages, such as SI5350C-Bxxxxx-GM1 or SI5350C-Bxxxxx-GM. Cross-family substitution with Si5351 requires verifying I2C compatibility and pin differences.

Clock Generators, PLLs, Frequency Synthesizers FAQ

Can the SI5350C-B03275-GT be reprogrammed after manufacturing?

No, this is a factory-programmed device. Reprogramming requires ordering a blank version (e.g., SI5350C-B-GT) and using ClockBuilder Pro software.

What reference frequencies are supported by this device?

The device supports a fixed-frequency crystal input of either 25 MHz or 27 MHz, or an external clock input via the CLKIN pin ranging from 10 to 100 MHz.

How many outputs does the SI5350C-B03275-GT provide?

The GT suffix indicates a 10-MSOP package which provides three independent clock outputs (CLK0, CLK1, and CLK2).
