SI5338M-B04513-GMR

Overview

The SI5338M-B04513-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 LVDS/LVPECL/CML formats, 350 MHz for SSTL/HSTL, 250 MHz for HCSL, and 200 MHz for CMOS. The device features low phase jitter of 0.7 ps RMS typical, zero ppm frequency accuracy, and glitchless frequency adjustments. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with independently configurable output voltages. Programming is performed via an I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four 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 adjustments in 1 ppm steps.

Applications

• PCIe Gen 1/2/3/4 systems
• Ethernet switch/router clocking
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix B04513 against the manufacturer's official documentation to confirm the programmed frequency plan and output configuration. Ensure the I²C pull-up voltage requirements are met if operating below 2.5 V. Confirm package type is 24-QFN (4x4 mm) and check for moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Verify that the input reference source matches the supported formats: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), or differential (5-710 MHz). Ensure the target output signal format and voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) align with the load requirements.

Part Context

The SI5338M-B04513-GMR belongs to the Si5338 family of I²C-programmable clock generators. This series replaces discrete crystal oscillators by providing flexible frequency synthesis. The 'GMR' suffix indicates a tape-and-reel packaging option suitable for automated surface-mount assembly. The device integrates NVM for storing configurations, reducing board space compared to multi-oscillator solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-model compatibility within the Si5338 family depends on specific frequency plans and output configurations defined by the unique ordering suffixes.
