SI5338M-B05024-GMR

Overview

The SI5338M-B05024-GMR is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA. It features low phase jitter of 0.7 ps RMS typ, flexible input references up to 710 MHz, and I2C/SMBus programming.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout configuration and factory pre-programming settings. Ensure the I2C pull-up voltage compatibility matches the system design, particularly if operating below 2.5 V.

Selection Notes

Select this component for designs requiring multiple independent clock frequencies from a single package. Confirm that the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) are supported by the target loads. Validate jitter requirements against the specific output format and load conditions specified in the electrical characteristics.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators and frequency translators. The device integrates a PLL and MultiSynth dividers to generate precise clock signals while maintaining low power consumption in a compact 4x4 mm QFN package.

Replacement Considerations

Direct replacements within the same family include SI5338A, SI5338B, SI5338F, SI5338J, and SI5338Q variants. Verify that the substitute part number matches the required output frequency range, jitter specifications, and specific output driver configurations.
