SI5350A-B06065-GTR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Si5350A-B06065-GTR is a factory-programmed CMOS clock generator manufactured by Skyworks Solutions. It utilizes a PLL and MultiSynth architecture to generate up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device operates on a core supply voltage (VDD) of 1.8 V, 2.5 V, or 3.3 V and an output supply voltage (VDDO) of 1.8 V, 2.5 V, or 3.3 V. It accepts a 25 MHz or 27 MHz crystal reference and features low output period jitter typically less than 70 ps pp. The component is housed in a 10-MSOP package providing three LVCMOS outputs.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates multiple independent, non-integer-related clock frequencies from a single fixed-frequency crystal reference.
• Supports configurable spread spectrum modulation on specific outputs to reduce electromagnetic interference.
• Allows pin-controlled glitchless frequency changes for designated outputs using frequency select pins.
• Features separate voltage supply domains for core logic and output buffers to facilitate level translation.

• Printers, scanners, and projectors
• Residential gateways and networking communication devices

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the factory-programmed configuration matches the target application requirements before integration. Confirm that the 10-MSOP package variant provides the necessary number of outputs. Ensure the external crystal specifications align with the internal load capacitance settings defined in the datasheet.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a fixed, custom frequency plan is required without I2C programming overhead. Compare against the Si5351 series if dynamic reconfiguration via I2C is needed. Verify that the maximum output count of three fits the system design constraints compared to higher-pin-count variants.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5350 family of factory-programmable clock generators. It serves as a cost-effective replacement for multiple discrete crystals and oscillators. The 'B' suffix indicates it is a factory-preprogrammed version, distinct from blank parts requiring user configuration.
