SI5342D-B02969-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5342D-B02969-GM is a jitter attenuating clock multiplier from the Si5342 Rev D family, manufactured by Skyworks Solutions Inc. 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 achieves ultra-low jitter of 90 fs rms and meets ITU-T G.8262 EEC Option 1 and 2 standards. Operating temperatures span from -40°C to +85°C with supply voltages of 1.8 V (VDD) and 3.3 V (VDDA).

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates any combination of output frequencies from any input frequency using fourth-generation DSPLL and MultiSynth technologies.
• Supports hitless input clock switching between fractionally related clocks and glitchless on-the-fly output frequency changes.
• Includes programmable jitter attenuation bandwidth ranging from 0.1 Hz to 4 kHz for optimized performance.
• Features in-circuit programmable non-volatile memory allowing known frequency configuration upon power-up.

Clock Generators, PLLs, Frequency Synthesizers Applications

• OTN muxponders and transponders
• 10/40/100 G networking line cards
• GbE/10 GbE/100 GbE Synchronous Ethernet compliant systems
• Carrier Ethernet switches

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix B02969 against official Skyworks documentation to confirm factory preprogrammed configuration details. Ensure compatibility with ClockBuilder Pro software settings for the designated NVM data. Confirm package availability and lead times through authorized distributors as standard stock levels vary.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when an ultra-low jitter solution under 350 MHz is required for applications like SyncE or OTN. The Si5342 variant provides two outputs, suitable for designs needing fewer channels than the Si5344 or Si5345. Verify that the input clock requirements align with the specified differential and LVCMOS ranges before finalizing the design.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5342 Rev D series, which integrates DSPLL and MultiSynth technologies. The 'D' designation indicates support for output frequencies up to 350 MHz. The 'B02969' suffix denotes a custom factory preprogrammed configuration assigned by Skyworks, distinct from generic programmable units.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5342A-D-GM offers a higher frequency range up to 1028 MHz. Si5342B-D-GM shares the 350 MHz limit but may differ in preprogramming. Si5344 and Si5345 variants provide additional output channels if more than two are needed.
