SI5342D-B05267-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5342D-B05267-GM is a factory preprogrammed jitter attenuator and clock multiplier from the Si5342 Rev D family. It features four differential inputs and two outputs, housed in a 44-QFN (7x7 mm) package. The device supports output frequencies up to 350 MHz with an ultra-low jitter performance of 90 fs rms. Operating voltage ranges from 1.71 V to 3.47 V, with a core supply of 1.8 V ±5% and analog supply of 3.3 V ±5%. It operates within a temperature range of –40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Combines fourth-generation DSPLL and MultiSynth technologies for any-frequency generation and jitter attenuation.
Includes in-circuit programmable non-volatile memory (NVM) to ensure known frequency configuration upon power-up.
Supports free-run, synchronous, and holdover modes with automatic or manual input clock switching.
Features fully integrated on-chip loop filter to eliminate discrete noise coupling risks.

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
SONET/SDH line cards

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering part number against the manufacturer's current documentation to confirm availability and revision status. Factory preprogrammed devices require unique numerical sequences assigned by Skyworks. Ensure compatibility with ClockBuilder Pro software for any necessary configuration overrides or verification of the NVM content prior to integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed, low-jitter clock solution is required without field programming. The Si5342 variant provides two outputs, suitable for designs needing fewer channels than the Si5344 or Si5345. Confirm that the 350 MHz maximum output frequency meets system requirements, as higher frequencies necessitate the 'A' or 'C' suffix variants.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5345/44/42 Rev D family, which utilizes DSPLL and MultiSynth technologies. The 'D' suffix indicates support for output frequencies up to 350 MHz. The 'B05267' sequence denotes a specific factory preprogrammed configuration stored in non-volatile memory, eliminating the need for external configuration during operation.
