SI5338N-B05936-GM

Overview

The SI5338N-B05936-GM 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 configurable signal formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device 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. It is housed in a compact 4 x 4 mm QFN-24 package and programmed via an I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables zero ppm precision frequency synthesis on four independent outputs.
• Configurable output drivers support various signal formats (LVPECL, LVDS, HCSL, CMOS, etc.) and voltages (1.5 V to 3.3 V).
• Low phase jitter performance of 0.7 ps RMS typical.
• Flexible input reference options including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router timing
• 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 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 source. Consider the specific output format requirements (differential vs. single-ended) and supply voltage needs for each driver during design.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The 'N' suffix typically denotes a specific factory-programmed frequency configuration, while 'GMR' indicates tape-and-reel packaging.

Replacement Considerations

Direct replacements within the same family include other Si5338 variants with different factory programming or output configurations. Verify that alternative parts match the required output frequencies and signal formats.
