SI5338C-B05006-GMR

Overview

The SI5338C-B05006-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm precision using MultiSynth technology. The device supports flexible input references including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz. Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats across frequencies up to 710 MHz. It operates on a single core supply of 1.8, 2.5, or 3.3 V within a 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth technology enables independent frequency synthesis on four drivers with 0 ppm accuracy
• Supports glitchless frequency adjustments via independent increment/decrement features
• Configurable spread spectrum generation with adjustable deviation and modulation rates
• Low phase jitter performance of 0.7 ps RMS typical

Applications

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

Procurement Notes

Verify the specific factory configuration code B05006 against the official datasheet ordering information table to confirm the programmed frequency set and output formats. Confirm that the GMR suffix corresponds to the required reel packaging quantity for production integration.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single low-jitter source. Ensure the required output signal formats match the supported LVPECL, LVDS, HCSL, or CMOS options. Verify that the input reference frequency falls within the specified ranges for crystal or digital inputs.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' indicates commercial temperature range operation (-40°C to +85°C). The 'B' denotes a specific factory pre-programmed configuration, while 'GMR' specifies tape and reel packaging.

Replacement Considerations

Direct pin-compatible replacements within the same family include other Si5338 variants with different factory codes. Verify that alternative part numbers support the identical output voltage levels and signal formats required by the target circuit design.
