SI5338N-B04336-GMR

Overview

The SI5338N-B04336-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. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is performed via an I²C/SMBus interface, allowing for flexible input references including crystals, CMOS, and differential clocks.

Feature Summary

• Four independent output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats
• Low phase jitter performance of 0.7 ps RMS typical
• I²C/SMBus compatible programming interface
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), and differential (5-710 MHz)

Applications

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

Procurement Notes

Verify the specific ordering suffix B04336 against the manufacturer's official documentation to confirm the programmed frequency plan and output configuration. Ensure compatibility with the required I²C bus voltage levels and check for moisture sensitivity classification prior to surface mount assembly.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Confirm that the desired output signal formats (LVDS, LVPECL, etc.) and voltage levels match the available driver configurations. Validate that the input reference source falls within the supported frequency ranges for the chosen input pin type.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The N suffix typically denotes a specific factory-programmed frequency plan and output configuration variant within the broader Si5338 product line, which shares the same underlying silicon and package architecture.

Replacement Considerations

Direct replacements must be from the Si5338 family with matching electrical characteristics and pinout. Verify that alternative SKUs provide the exact same programmed frequencies and output drive strengths to ensure functional equivalence without hardware redesign.
