SI5395L-A-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5395L-A-GM is a jitter attenuator and clock multiplier featuring an integrated reference oscillator. It provides four inputs and twelve outputs within a 64-LGA package. The device supports integer-only frequency synthesis with output frequencies ranging from 0.0001 MHz to 1028 MHz. Input frequencies are accepted in differential (8 kHz to 750 MHz) or LVCMOS (8 kHz to 250 MHz) formats. Operating voltage ranges from 1.71 V to 3.47 V, with a typical supply current of 150 mA. It 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 latest documentation to confirm factory preprogramming requirements. Confirm package type compatibility, as LGA variants differ from QFN versions. Ensure serial interface configuration matches system design constraints before finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this grade when an integrated reference is required to save board space and improve reliability. This model supports integer-only synthesis; fractional mode requires Grade J or K. Verify that the application does not require external crystal connections, as connecting external references to integrated grades may cause damage.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5395 family, which combines fourth-generation DSPLL and Multi-Synth technologies. It serves as a drop-in replacement for the Si5345 series. The L-grade specifically utilizes an internal oscillator, distinguishing it from A/B/C/D/P grades that require external crystals.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5395J-A-GM offers identical packaging and pinout but adds fractional synthesis capabilities. Si5395A-A-GM provides similar functionality but requires an external crystal reference instead of an integrated one.
