SI5338B-B04183-GMR

Overview

The SI5338B-B04183-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis on four output drivers. It supports any-frequency generation with zero ppm precision and features low phase jitter of 0.7 ps RMS typical. The device accepts various input references including differential clocks up to 710 MHz and single-ended inputs up to 200 MHz. Outputs are configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V per driver. It operates from a single core supply of 1.8, 2.5, or 3.3 V within a 24-lead QFN package.

Procurement Notes

Verify the specific B04183 factory code against the manufacturer's current ordering information to confirm availability and exact configuration parameters. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling instructions during storage and assembly.

Selection Notes

Select this component when designing systems requiring four independent clock signals with precise frequency accuracy and low jitter. Consider the required output voltage levels and signal formats (LVPECL, LVDS, etc.) to ensure the configurable drivers meet the load requirements. Verify that the input reference source matches the supported frequency ranges and coupling methods.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'B' suffix typically denotes a specific factory code or initial configuration variant within the series. The '-GMR' suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly in a 24-lead QFN package.

Replacement Considerations

Direct replacements within the Si5338 family may require reprogramming via ClockBuilder Pro software to match the specific frequency and format configurations. Verify pinout compatibility and electrical specifications, particularly output drive strength and supply voltage ranges, before substituting other models.
