SI5338M-B10099-GM

Overview

The SI5338M-B10099-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. It operates within a core supply voltage range of 1.71 V to 3.63 V and supports input frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical, configurable output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, and allows independent output voltage selection per driver. It is housed in a compact 4 x 4 mm QFN-24 package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers with true zero ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical across LVPECL, LVDS, HCSL, and CML output formats.
• Flexible input reference options supporting external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Independent output voltage configuration per driver at 1.5, 1.8, 2.5, or 3.3 V, alongside glitchless frequency adjustment capabilities.

Applications

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

Procurement Notes

Verify the specific ordering suffix B10099 against official Skyworks documentation to confirm the programmed frequency plan and output configuration. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling instructions during assembly.

Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single source with high precision. Consider the output format requirements (LVPECL, LVDS, etc.) and verify that the input reference signal matches the supported frequency ranges. Evaluate power consumption based on the selected output loads and frequencies.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'B' suffix indicates a factory-programmed variant with fixed frequency settings, distinguishing it from blank devices. The 'GM' suffix denotes the 24-lead QFN package type used for space-constrained PCB layouts.

Replacement Considerations

Direct replacements must be sought from the Si5338 family with matching programming suffixes. Verify pinout compatibility and electrical specifications, particularly output drive strength and jitter performance, before substituting other clock generator models.
