SI5345D-B00002-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5345D-B00002-GM is a 10-output jitter attenuator and clock multiplier featuring fourth-generation DSPLL and MultiSynth technologies. It supports any-frequency generation from differential inputs up to 750 MHz or LVCMOS inputs up to 250 MHz, producing outputs ranging from 100 Hz to 350 MHz. The device operates on a 1.8 V core supply (VDD) and a 3.3 V analog supply (VDDA), with independent output supplies configurable for 3.3 V, 2.5 V, or 1.8 V. It utilizes a 64-pin QFN package measuring 9x9 mm and functions within a temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm factory preprogramming details. Confirm package availability and lead times through authorized distributors. Ensure compatibility with ClockBuilder Pro software versions for configuration. Check for end-of-life status or alternative recommendations from Skyworks Solutions.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model for applications requiring 10 outputs with frequencies up to 350 MHz. Choose based on the need for low jitter attenuation and flexible input/output voltage levels. Consider the 64-QFN package size for PCB layout constraints. Verify that the required input frequency range fits within the specified differential or LVCMOS limits.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345 family of jitter attenuators. It shares the same package and core architecture as the Si5345A, B, and C variants, differing primarily in maximum output frequency capabilities and synthesis modes. The 'D' suffix indicates support for output frequencies up to 350 MHz with both integer and fractional synthesis.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5345B-D-GM offers similar functionality but may have different factory programming. Si5345A-D-GM provides higher output frequency support up to 1028 MHz. Verify pinout and register compatibility before substitution.
