SI5338C-B05079-GM

Overview

The SI5338C-B05079-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 accepts flexible input references up to 710 MHz. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum output frequency of 710 MHz for differential outputs, and an operating temperature range of –40 °C to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports highly configurable output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• Features low phase jitter (0.7 ps RMS typ) and glitchless frequency adjustments via independent increment/decrement features.
• Programmable via I2C/SMBus interface using ClockBuilder Pro software.

Applications

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

Procurement Notes

Verify the specific ordering suffix B05079 against the manufacturer's current datasheet to confirm the exact pre-configured frequency plan and output format. Ensure compatibility with the required input reference source and output load conditions before procurement.

Selection Notes

Select this component when replacing multiple discrete oscillators with a single programmable solution. Verify that the required output frequencies fall within the supported ranges for the chosen signal format (e.g., up to 710 MHz for LVDS/LVPECL). Confirm that the system design accommodates the 24-lead QFN package dimensions.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' in the model number typically denotes a specific factory configuration or frequency plan, while 'GM' indicates the lead-free QFN-24 package. It serves as a drop-in replacement for fixed-frequency crystal oscillators in high-performance digital systems.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. When replacing, ensure the new component matches the pinout, voltage levels, and jitter performance requirements of the original design.
