SI5338M-B04370-GMR

Overview

The SI5338M-B04370-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, HCSL, CMOS, CML, 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 glitchless frequency adjustments via I2C/SMBus interface.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers
• Low phase jitter of 0.7 ps RMS typ with high precision zero ppm frequency accuracy
• Highly-configurable output drivers supporting up to four differential outputs, eight single-ended outputs, or combinations
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential (5-710 MHz)

Applications

• Ethernet switch/router
• PCIe Gen1/2/3/4
• Broadcast video/audio timing
• Processor and FPGA clocking
• MSAN/DSLAM/PON

Procurement Notes

Verify the specific ordering suffix B04370 against the manufacturer's official documentation to confirm pre-programmed register settings and factory configuration. Ensure compatibility with the required I2C address and output format specifications for the target application design.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single programmable source. Verify that the required output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Confirm power supply voltage requirements match the available system rails.

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. It is designed to replace up to four different frequency crystal oscillators or operate as a frequency translator in space-constrained applications using a 4x4 mm QFN package.
