SI5338A-B06137-GMR

Overview

The SI5338A-B06137-GMR is an I2C-programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with 0 ppm precision and a typical phase jitter of 0.7 ps RMS. The device supports differential inputs up to 710 MHz and single-ended inputs up to 350 MHz. Outputs include LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats, each independently configurable for voltage levels of 1.5, 1.8, 2.5, or 3.3 V. It operates from a single core supply (1.8, 2.5, or 3.3 V) within a -40 to +85 °C temperature range in a 24-lead QFN package.

Procurement Notes

Verify the specific ordering suffix B06137 against the manufacturer's current documentation to confirm factory programming parameters. Confirm the RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the I2C pull-up voltage requirements are met by the system design.

Selection Notes

Select this component when zero ppm frequency accuracy and low jitter (<1 ps RMS) are required for high-speed serial interfaces like PCIe Gen 3/4. Verify that the target application utilizes differential inputs up to 710 MHz or requires mixed single-ended/differential output configurations. Ensure the system power budget accommodates the typical 45 mA core supply current.

Part Context

This part belongs to the Si5338 family of programmable clock generators. The 'A' designation typically indicates the highest performance tier within the series, supporting frequencies up to 710 MHz. The 'GMR' suffix denotes a tape-and-reel packaging format suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements within the same family include SI5338A-B-GM or SI5338A-B-GMR. These variants share identical electrical specifications and pinouts but may differ in factory programming or packaging quantity. Verify register compatibility if migrating between pre-programmed and blank variants.
