SI5338C-B05629-GM

Overview

The SI5338C-B05629-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency with zero ppm precision on four independent outputs. It operates within a core supply range of 1.71 V to 3.63 V and supports output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device features low phase jitter (0.7 ps RMS typ) and accepts differential inputs up to 710 MHz or single-ended inputs up to 200 MHz. Encased in a 4x4 mm QFN-24 package, it allows independent voltage configuration per driver.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four drivers with 0 ppm accuracy
• Flexible input support: external crystals (8–30 MHz), CMOS (5–200 MHz), and differential (5–710 MHz)
• Independent output voltage selection (1.5, 1.8, 2.5, or 3.3 V) for each driver
• Glitchless frequency adjustment via independent increment/decrement feature

Applications

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

Procurement Notes

Verify the specific factory programming code associated with the B05629 suffix against the official Skyworks ordering guide. Confirm that the required output frequencies and signal formats match the programmed configuration, as this variant is pre-configured at the factory.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single flexible source. Ensure the target application requires independent voltage levels for different loads, as the Si5338 supports distinct VDDO settings per output driver.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' indicates a specific performance grade or revision, while 'B05629' denotes the unique factory programming pattern defining the output frequencies and configurations.

Replacement Considerations

Direct pin-to-pin replacements within the Si5338 family may exist but require verification of the internal programming data. Compare the specific output frequencies and jitter requirements of the legacy component against the Si5338 capabilities.
