SI5338L-B05700-GM

Overview

The SI5338L-B05700-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis on four output drivers. It supports any frequency up to 350 MHz with zero ppm precision and features low phase jitter of 0.7 ps RMS typical. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and accepts various input references including differential clocks up to 710 MHz. It is housed in a compact 4 x 4 mm QFN-24 package.

Feature Summary

• Four independent outputs supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input reference options: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), or differential (5–710 MHz)
• Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V

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 B05700 against official Skyworks documentation to confirm factory-programmed parameters. Confirm package type and RoHS compliance status prior to procurement. Ensure I2C bus voltage compatibility with the selected core supply voltage.

Selection Notes

Select this model for applications requiring four independent clock outputs with frequencies up to 350 MHz. Ensure the design accommodates the required output voltage levels (1.5V to 3.3V) and input reference types. Verify thermal requirements for the QFN-24 package under maximum load conditions.

Part Context

This component belongs to the Si5338 family of I2C-programmable clock generators. The 'L' suffix typically denotes specific output configuration or enable pin control variations within the family, while 'B05700' indicates a custom factory-programmed frequency plan. The '-GM' suffix identifies the lead-free QFN-24 package variant.

Replacement Considerations

Direct replacements must match the Si5338 family specifications. Verify that alternative part numbers support the same 350 MHz maximum output frequency and QFN-24 footprint. Check if the replacement supports the required output formats and jitter performance.
