SI5344A-B05173-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5344A-B05173-GM is a factory preprogrammed clock synthesizer and jitter attenuator belonging to the Si5344 family. It features four inputs and four outputs housed in a 44-QFN package measuring 7x7 mm. The device supports integer and fractional frequency synthesis, generating output frequencies ranging from 0.001 MHz to 1028 MHz. It operates within a temperature range of -40°C to +85°C and utilizes DSPLL technology for ultra-low jitter performance.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

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

• 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 B05173 suffix against official Skyworks documentation to confirm the exact preprogrammed frequency plan and configuration parameters. Factory preprogrammed devices require precise part number matching to ensure correct operational settings upon installation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when requiring four differential or single-ended outputs with frequencies up to 1028 MHz. Ensure compatibility with LVDS, LVPECL, LVCMOS, CML, or HCSL output formats. Verify that the required jitter attenuation bandwidth and input frequency ranges align with the device specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Si5344 Rev D series, which includes variants like the SI5344A-D-GM. The 'A' designation indicates support for both integer and fractional synthesis modes up to 1028 MHz. The 'B05173' suffix identifies a custom factory preprogrammed configuration rather than a blank prototyping device.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

SI5344A-D-GM serves as the generic equivalent for blank programming. For applications requiring identical pinouts but different preprogrammed configurations, other B-suffixed parts within the Si5344 family may be suitable if frequency plans match.
