SI5338M-B05735-GM

Overview

The SI5338M-B05735-GM is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz for LVDS/LVPECL/CML formats, 350 MHz for SSTL/HSTL, and 200 MHz for CMOS. The device features low phase jitter of 0.7 ps RMS typical, independent output voltage configurations (1.5, 1.8, 2.5, or 3.3 V), and I2C/SMBus programming. It operates on a single core supply of 1.8, 2.5, or 3.3 V within an operating temperature range of –40 to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Low phase jitter performance of 0.7 ps RMS typical across all outputs.
• Highly configurable output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), 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 clocking
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific factory-programmed configuration associated with the B05735 suffix against the system requirements using Skyworks ClockBuilder Pro software. Confirm that the QFN-24 package dimensions and thermal characteristics align with the PCB land pattern recommendations in the datasheet.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Ensure the target output signal format (LVDS, CMOS, etc.) and voltage levels match the load requirements. Verify that the input reference source falls within the supported frequency ranges for the chosen input pin configuration.

Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. The 'M' suffix typically denotes a specific factory-programmed configuration variant within the series, distinct from user-programmable versions like the Si5338Q or Si5338N.

Replacement Considerations

Direct replacements must be sought from the Si5338 family with matching factory-programmed parameters. Cross-referencing with other Skyworks clock generators requires verifying compatibility with MultiSynth architecture and output driver specifications.
