SI5338J-B05415-GMR

Overview

The SI5338J-B05415-GMR 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 formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates with a core supply of 1.8, 2.5, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Input references range from external crystals (8–30 MHz) to differential inputs up to 710 MHz. Outputs are configurable for frequencies up to 710 MHz, with individual voltage levels selectable at 1.5, 1.8, 2.5, or 3.3 V.

Procurement Notes

Verify the specific ordering suffix B05415 against the manufacturer's official documentation to confirm the exact pre-configured frequency plan and pinout assignment. 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 independent frequency synthesis across multiple domains without external oscillators. Consider the output format requirements (LVDS vs CMOS) and voltage levels (1.8V vs 3.3V) for each driver. Verify that the input reference source matches the supported frequency ranges and signal types specified in the electrical characteristics.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'J' variant typically denotes a specific factory-programmed configuration within the series. The '-GMR' suffix indicates a tape-and-reel packaging option suitable for automated surface-mount assembly. The device replaces discrete crystal oscillators and frequency translators in complex digital systems.

Replacement Considerations

Direct replacements within the Si5338 family require matching the specific B05415 configuration file. Generic Si5338 devices must be reprogrammed via I2C to replicate the exact frequency, duty cycle, and output format settings. Verify package compatibility (24-QFN) and thermal characteristics if substituting with other variants.
