SI5338M-B04405-GMR

Overview

The SI5338M-B04405-GMR is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four output drivers with zero ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and features independent output voltage configurations. Key electrical parameters include a maximum input frequency of 710 MHz, a typical phase jitter of 0.7 ps RMS, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

• MultiSynth™ Technology: Generates four independent clocks with 0 ppm frequency accuracy.
• Flexible Output Formats: Supports LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• Low Jitter Performance: Typical RMS phase jitter of 0.7 ps for GbE and PCIe applications.
• Glitchless Frequency Adjustment: Independent frequency increment/decrement in 1 ppm steps.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout configuration and output enable control logic. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling instructions during storage and assembly.

Selection Notes

Select this component when low jitter synthesis is required for high-speed serial interfaces like PCIe or Ethernet. Confirm that the desired output signal formats (differential vs. single-ended) and voltage levels match the target receiver specifications. Verify input reference frequency ranges against available crystal or oscillator sources.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete oscillators by providing any-frequency synthesis on four outputs within a compact 4x4 mm QFN package. The device integrates NVM programming capabilities for standalone operation after initial configuration.
