SI5338C-B04167-GM

Overview

The SI5338C-B04167-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 formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates with a 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 accepts flexible input references up to 710 MHz and allows glitchless frequency adjustments via I2C/SMBus.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with zero ppm precision.
• Supports PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliance with low phase jitter of 0.7 ps RMS typical.
• Highly-configurable outputs support LVPECL/LVDS (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), and SSTL/HSTL (up to 350 MHz).
• Independent output voltage per driver selectable at 1.5, 1.8, 2.5, or 3.3 V.

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 factory-programmed configuration associated with the B04167 suffix against the target design requirements. Confirm package availability and lead times through authorized distributors as standard stock levels may vary. Ensure I2C programming tools like ClockBuilder Pro are available for final validation if custom modifications are needed.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single IC. Verify that the desired output formats (LVPECL, LVDS, CMOS, etc.) and frequencies fall within the specified limits for each driver. Check that the input reference source matches the supported types, such as external crystals (8-30 MHz) or differential inputs (up to 710 MHz).

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. It replaces discrete crystal oscillators and serves as a frequency translator. The device integrates a PLL and MultiSynth stages in a compact 4x4 mm QFN-24 package, designed for space-constrained high-performance digital systems.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory configurations. Ensure the replacement part supports the required output frequencies and signal formats. Cross-model substitution requires verifying register compatibility and electrical specifications.
