SI5338A-B01086-GM

Overview

The SI5338A-B01086-GM is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. It supports input frequencies up to 710 MHz and generates outputs ranging from 0.16 MHz to 710 MHz depending on the format (LVPECL, LVDS, HCSL, CMOS, etc.). The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, drawing a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS typ, glitchless frequency adjustments, and spread spectrum capabilities. Configuration is managed via an I2C/SMBus interface.

Feature Summary

• Four independent output drivers supporting any frequency synthesis with 0 ppm accuracy
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input options including external crystals (8-30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz
• Configurable output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS applications
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON systems

Procurement Notes

Verify the specific ordering suffix B01086 against the manufacturer's latest datasheet to confirm factory-programmed frequency settings. Ensure the package type matches the required PCB land pattern for the 24-QFN form factor. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single source. Verify that the desired output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Check if the input reference frequency falls within the supported ranges for the chosen input mode (differential vs. single-ended).

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'A' designation typically indicates a specific speed grade or feature set within the series, while 'B01086' denotes a pre-programmed configuration. The 'GM' suffix identifies the 24-lead QFN package variant.

Replacement Considerations

Direct replacements must be from the Si5338 family with compatible pinouts and electrical characteristics. Verify that alternative part numbers support the same output formats and frequency ranges. Cross-reference programming files if migrating between different factory-configured variants.
