SI5338M-B05847-GMR

Overview

The SI5338M-B05847-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz for LVPECL/LVDS/CML formats. The device features low phase jitter of 0.7 ps RMS typical, 0 ppm frequency accuracy, and glitchless frequency adjustments via I2C/SMBus interface. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V within an operating temperature range of –40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Low phase jitter of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Highly-configurable output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.
• Independent frequency increment/decrement feature allows glitchless frequency adjustments in 1 ppm steps.

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Processor and FPGA clocking
• Telecom line cards
• Fibre Channel, SAN

Procurement Notes

Verify the specific ordering suffix B05847 against the manufacturer's current documentation to confirm factory-programmed parameters. Ensure compatibility with the required input reference frequency and output signal formats before integration. Confirm package availability and moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Verify that the desired output frequencies fall within the supported ranges for the chosen output format (e.g., 710 MHz max for LVPECL). Ensure the system design accommodates the 4x4 mm QFN-24 package dimensions and thermal requirements.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'M' suffix typically denotes a specific factory-programmed configuration variant within the series. The '-GMR' suffix indicates tape and reel packaging suitable for automated surface-mount assembly.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants such as SI5338A, SI5338B, SI5338J, or SI5338K, provided their programmed frequencies and output configurations match the design requirements. Always verify electrical specifications and programming software compatibility.
