SI5338M-B05693-GM

Overview

The SI5338M-B05693-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with configurable signal formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. It is housed in a compact 4x4 mm QFN-24 package and programmed via an 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 typical for high-performance timing applications
• Highly-configurable output drivers supporting up to four differential or eight single-ended outputs
• Flexible input reference options including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router clocking
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON equipment

Procurement Notes

Verify the specific ordering suffix B05693 against the manufacturer's current datasheet to confirm factory-programmed parameters. Ensure compatibility with the required I2C address and output configurations before procurement. Check for RoHS compliance status as indicated in the official documentation.

Selection Notes

Select this component when zero ppm frequency accuracy and low jitter are critical for multiple independent clocks. Consider the available output voltage levels (1.5 V, 1.8 V, 2.5 V, 3.3 V) and signal formats required by the destination devices. Verify that the input reference frequency falls within the supported ranges for the chosen configuration.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'M' suffix typically denotes specific output enable control characteristics, while 'B05693' indicates custom factory programming. The 'GM' suffix signifies the lead-free QFN-24 package variant.

Replacement Considerations

Direct replacements within the Si5338 family require matching the output count, frequency range, and jitter specifications. Verify that alternative part numbers support the same I2C programming interface and physical footprint. Custom programmed parts may not have direct pin-to-pin equivalents without reprogramming.
