SI5338N-B05174-GMR

Overview

The SI5338N-B05174-GMR is an I2C-programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports flexible input references, including external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz). Outputs are configurable for various formats such as LVPECL, LVDS, HCSL, and CMOS, with independent voltage levels of 1.5, 1.8, 2.5, or 3.3 V. Key electrical parameters include a core supply voltage range of 1.71 V to 3.63 V, typical operating current of 45 mA, and low phase jitter of 0.7 ps RMS.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with true zero ppm accuracy.
• Supports highly configurable output drivers capable of up to four differential outputs, eight single-ended outputs, or mixed configurations.
• Features glitchless frequency adjustments via independent increment/decrement in 1 ppm steps and independent phase adjustment with <20 ps resolution.
• Includes flexible spread spectrum generation with adjustable deviation (0.5% to 5.0%) and modulation rates (33 to 63 kHz).

Applications

• PCIe Gen 1/2/3/4 common clock and Gen 3 SRNS compliant timing
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking systems
• Telecom line cards and MSAN/DSLAM/PON equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm factory programming and package variations. Ensure compatibility with ClockBuilder Pro software for configuration. Check for moisture sensitivity levels and recommended reflow profiles during assembly.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single programmable source. Ensure the required output frequencies fall within the supported ranges: LVPECL/LVDS up to 710 MHz, HCSL up to 250 MHz, and CMOS up to 200 MHz. Verify that the available input reference matches the device's supported formats.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The series is designed to replace crystal oscillators and function as frequency translators. It is housed in a compact 4 x 4 mm 24-lead QFN package suitable for space-constrained designs.

Replacement Considerations

Direct pin-compatible replacements within the same family may exist but require verification of specific frequency plans and output configurations. Consult the manufacturer's cross-reference tools for validated substitutes.
