SI5342D-B06182-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5342D-B06182-GM is a low-jitter clock synthesizer and jitter cleaner from Skyworks Solutions. It features four inputs and two outputs, housed in a 44-QFN package measuring 7x7 mm. 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 achieves ultra-low jitter of 90 fs rms and operates within a temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Supports highly configurable outputs compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL formats.
• Includes in-circuit programmable non-volatile memory for known frequency configuration at power-up.
• Provides automatic and manual hitless input clock switching capabilities.

Clock Generators, PLLs, Frequency Synthesizers Applications

• OTN muxponders and transponders
• 10/40/100 G networking line cards
• GbE/10 GbE/100 GbE Synchronous Ethernet (ITU-T G.8262)
• Carrier Ethernet switches

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the B06182 suffix against project requirements before procurement. Confirm that the 44-QFN 7x7 mm package dimensions align with the PCB land pattern design. Ensure compatibility with the required serial interface protocol and voltage levels for the target system integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a two-output solution is sufficient, as opposed to the four or ten-output variants in the Si5342/44/45 family. The 'D' designation indicates support for integer and fractional synthesis modes with an output frequency range up to 350 MHz. Verify that the 90 fs rms jitter performance meets the strict timing requirements of the application.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5342 Rev D series, which utilizes MultiSynth and DSPLL technologies. It is part of a broader family including the Si5344 and Si5345, differentiated primarily by the number of available output clocks. The Si5342 specifically provides two outputs within a compact 44-pin QFN footprint.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct functional replacements include other Si5342 variants such as SI5342A-D-GM or SI5342C-D-GM, depending on whether higher frequency ranges or integer-only synthesis are required. Cross-family substitution with Si5344 or Si5345 models is possible if additional output channels are needed, provided pinout compatibility is verified.
