SI5338N-B05414-GM

Overview

The SI5338N-B05414-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Maximum input frequency reaches 710 MHz via differential inputs, while outputs support up to 710 MHz for LVPECL/LVDS/CML formats. Core supply voltage ranges from 1.71 V to 3.63 V (1.8/2.5/3.3 V nominal). Typical phase jitter is 0.7 ps RMS. Operating temperature spans -40 °C to +85 °C in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Flexible input references include external crystals (8–30 MHz), CMOS (5–200 MHz), and differential signals (5–710 MHz).
• Configurable output drivers support multiple signal formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• Features glitchless frequency adjustment in 1 ppm steps and independent phase adjustment with <20 ps resolution.

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant timing
• Ethernet switch/router clocking
• Processor and FPGA clock generation
• Broadcast video/audio timing systems

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B05414 suffix against design requirements. Confirm I2C/SMBus interface compatibility and power supply levels (1.8 V, 2.5 V, or 3.3 V) prior to integration. Ensure PCB land pattern matches the 4 x 4 mm QFN outline.

Selection Notes

Select this component when replacing multiple crystal oscillators with a single programmable source. Verify that required output frequencies fall within the supported ranges for the chosen driver format (e.g., 710 MHz max for LVPECL vs. 200 MHz for CMOS). Check if independent phase or frequency increment/decrement features are necessary for the system architecture.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' designation typically indicates a custom factory-programmed variant with specific frequency configurations stored in non-volatile memory. The '-GMR' suffix denotes tape-and-reel packaging for surface-mount assembly.

Replacement Considerations

Direct pin-to-pin replacements within the Si5338 family may require reprogramming or different NVM configurations. Verify that alternative SKUs support the same output formats and frequency ranges. Consult Skyworks documentation for specific substitution guidelines regarding electrical characteristics and thermal performance.
