SI5338M-B04828-GM

Overview

The SI5338M-B04828-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent outputs with 0 ppm precision and low jitter of 0.7 ps RMS typical. The device supports input frequencies up to 710 MHz and output formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Powered by a single core supply of 1.8 V, 2.5 V, or 3.3 V, it operates within a temperature range of -40 °C to +85 °C in a 4x4 mm QFN-24 package.

Feature Summary

• I2C-programmable synthesis with 0 ppm frequency accuracy
• Four independent outputs supporting differential and single-ended formats
• Low phase jitter of 0.7 ps RMS typical
• Flexible input reference: external crystal (8–30 MHz), CMOS, SSTL/HSTL, or differential (up to 710 MHz)

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm configuration details such as output enable control and spread spectrum settings. Ensure compatibility with I2C bus voltage levels and check for moisture sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when independent frequency synthesis across four channels is required. Confirm that the target output signal format (LVPECL, LVDS, etc.) and voltage levels match the application needs. Verify input source compatibility, whether crystal, single-ended, or differential, before finalizing the design.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The 'M' suffix typically denotes specific output enable control configurations, while the numeric code defines the factory-programmed frequency plan. It replaces multiple discrete oscillators in complex system designs.

Replacement Considerations

Direct pin-to-pin replacements within the same family require identical frequency plans and output configurations. Verify electrical parameters and software programming files for equivalent performance characteristics.
