SI5338N-B04337-GM

Overview

The SI5338N-B04337-GM is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates from 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.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers
• Low phase jitter of 0.7 ps RMS typical
• Flexible input reference supporting external crystals (8-30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz
• Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Processor and FPGA clocking
• Telecom line cards
• 1 GbE and 10 GbE

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout configuration and factory programming settings. Ensure compatibility with the required I2C bus voltage levels for system integration.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Verify that the desired output signal formats (LVPECL, LVDS, etc.) and frequencies fall within the supported ranges specified in the datasheet.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The family offers space-saving 4x4 mm QFN packaging and supports glitchless frequency adjustments and spread spectrum generation.

Replacement Considerations

Consult the official Skyworks Solutions cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence with other clock generators without verifying pinout and electrical specifications.
