SI5342D-B03062-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5342D-B03062-GMR is a jitter attenuator and clock multiplier from Skyworks Solutions Inc. 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 an 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

• Generates any combination of output frequencies from any input frequency using fourth-generation DSPLL technology.
• Supports hitless input clock switching with automatic or manual selection capabilities.
• Includes in-circuit programmable non-volatile memory for known power-up configurations.
• Provides glitchless on-the-fly output frequency changes and DCO mode operation.

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 suffix against the manufacturer's current documentation to confirm tape and reel packaging requirements. Ensure the preprogrammed configuration matches the target application design. Confirm RoHS compliance status and lead times directly with authorized distributors prior to finalizing procurement orders.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when only two differential or single-ended output clocks are required, as it differs from the Si5344 and Si5345 which offer four and ten outputs respectively. Verify that the maximum output frequency requirement does not exceed 350 MHz, as higher frequency variants exist within the family. Ensure the serial interface and NVM programming needs align with the ClockBuilder Pro software workflow.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the Si5345/44/42 Rev D family of jitter attenuators. It shares core architecture with the Si5344 and Si5345 but is distinguished by its reduced pin count and output channel availability. The 'D' designation indicates support for integer and fractional synthesis modes up to 350 MHz, differentiating it from integer-only or higher-frequency variants.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Si5342A-D-GMR provides similar functionality but supports output frequencies up to 1028 MHz instead of 350 MHz. Si5344D-GMR offers four outputs instead of two within the same package footprint. Verify electrical compatibility and pinout alignment before substituting these family members.
