SI5338B-B06190-GMR

Overview

The SI5338B-B06190-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 up to 710 MHz with zero ppm precision and features low phase jitter of 0.7 ps RMS typical. The device accepts various input references including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz). Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats with independent supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a single core supply of 1.8, 2.5, or 3.3 V, draws 45 mA typical current, and functions within a temperature range of –40 to +85 °C in a 24-lead QFN package.

Procurement Notes

Verify the specific B06190 factory configuration against the datasheet's ordering information table to ensure correct pinout and output enable logic. Confirm that the GMR suffix indicates tape-and-reel packaging suitable for automated assembly. Check for RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring four independent clock signals with precise frequency accuracy and low jitter. Ensure the target application supports the required input reference frequencies and output voltage levels. Consider the I2C programming interface requirements and utilize ClockBuilder Pro software for optimal configuration. Verify thermal management needs given the 45 mA typical core supply current and QFN-24 package thermal characteristics.

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. The 'B' designation typically refers to a specific factory configuration or output enable logic variant within the series. The 'GMR' suffix denotes the reel packaging format. This model replaces discrete crystal oscillators by synthesizing multiple clock domains from a single reference source.

Replacement Considerations

Direct replacements within the Si5338 family include other pre-configured variants such as SI5338A, SI5338J, or SI5338Q, depending on the required output frequency range and format. Verify that the substitute part matches the specific B06190 configuration parameters, including output enable control logic and default state settings, to ensure functional compatibility without hardware redesign.
