SI5338B-B06189-GMR

Overview

The SI5338B-B06189-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency with zero ppm accuracy on four independent output drivers. The device supports flexible input references, including differential inputs up to 710 MHz and CMOS inputs up to 200 MHz. Output formats include LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL, with frequencies ranging from 0.16 MHz to 710 MHz depending on the format. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, consuming approximately 45 mA. The component features low phase jitter of 0.7 ps RMS typical and is housed in a 24-lead QFN package.

Procurement Notes

Verify the specific configuration encoded in the suffix B06189 against the target design requirements using Skyworks ClockBuilder Pro software. Confirm that the I2C programming parameters match the system's electrical constraints. Ensure the 24-QFN package land pattern adheres to the recommended PCB layout guidelines for thermal and signal integrity.

Selection Notes

Select this model when independent frequency synthesis across four outputs is required without fixed crystal limitations. Ensure the application supports the necessary input reference type, whether differential, single-ended CMOS, or external crystal. Verify that the output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) align with the receiving device specifications for each driver.

Part Context

This part belongs to the Si5338 family of high-performance, low-jitter clock generators. It replaces multiple discrete oscillators by providing four independent clock signals from a single source. The device integrates an I2C interface for configuration and supports spread spectrum modulation for EMI reduction.

Replacement Considerations

Direct pin-to-pin replacements within the same family require identical frequency and format configurations. Consult the manufacturer's substitution guide for verified equivalents with matching electrical characteristics and package dimensions.
