SI5342D-D06495-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5342D-D06495-GM is a factory preprogrammed jitter attenuator and clock multiplier from the Si5342 Rev D family. It features four inputs and two outputs housed in a 44-QFN (7x7 mm) package. The device supports differential input frequencies from 8 kHz to 750 MHz and LVCMOS inputs up to 250 MHz. Output frequencies range from 100 Hz to 350 MHz for differential signals and up to 250 MHz for LVCMOS. It operates on a core voltage of 1.8 V ±5% and an I/O supply of 3.3 V ±5%, with an operating temperature range of –40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific configuration associated with the suffix D06495, as this indicates a factory preprogrammed part number assigned by Skyworks. Confirm that the preloaded frequency plan matches the target application requirements before procurement, as these devices are not field-reconfigurable without overriding the non-volatile memory settings.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the Si5342 variant when only two output clocks are required, distinguishing it from the four-output Si5344 and ten-output Si5345 models. Ensure the design accommodates the 44-QFN 7x7 mm package dimensions and utilizes the ClockBuilder Pro software for initial configuration if custom programming is needed prior to ordering.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D series, which integrates MultiSynth and DSPLL technologies. The Si5342 specifically provides a compact solution for applications requiring minimal output channels while maintaining high-performance jitter attenuation and flexible input/output configurations within a small form factor.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other Si5342 variants such as Si5342A-D-GM or Si5342B-D-GM, provided their frequency ranges and synthesis modes align with the system requirements. Cross-family substitution with Si5344 or Si5345 is possible but requires pinout and register compatibility verification.
