SI5338K-B05615-GMR

Overview

The SI5338K-B05615-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis on four output drivers. It supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device accepts inputs up to 710 MHz and generates outputs with 0 ppm precision. Key electrical parameters include a core supply voltage range of 1.71 V to 3.63 V, typical operating current of 45 mA, and low phase jitter of 0.7 ps RMS. It operates within an ambient temperature range of –40 °C to +85 °C.

Procurement Notes

Verify the specific factory programming code B05615 against the target design requirements using ClockBuilder Pro software. Confirm that the QFN-24 package dimensions and thermal characteristics meet the PCB layout constraints. Ensure the I2C pull-up voltages align with the supported range of 1.71 V to 3.63 V.

Selection Notes

Select this component when four independent clock signals with varying frequencies or formats are required from a single source. The Si5338K variant typically implies specific pinout or feature configurations; verify the exact pin assignments and output enable controls via the datasheet's ordering information section. Consider the 45 mA typical current consumption for power budget calculations.

Part Context

This part belongs to the Si5338 family of high-performance, low-jitter clock generators. The 'K' suffix in the model number indicates a specific hardware revision or pinout configuration within the Si5338 series. The 'GMR' suffix denotes tape-and-reel packaging suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements must match the Si5338 family specifications. Verify compatibility with existing firmware or configuration files generated by ClockBuilder Pro. Check if the replacement part shares the same pinout and electrical characteristics, particularly the core supply voltage and output driver capabilities.
