SI5338C-B05078-GM

Overview

The SI5338C-B05078-GM is a programmable clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz, achieving 0 ppm precision. The device operates from a 1.8 V, 2.5 V, or 3.3 V core supply with typical current consumption of 45 mA. Key electrical parameters include a maximum input frequency of 710 MHz, a typical phase jitter of 0.7 ps RMS, 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 zero ppm accuracy.
• Supports flexible input references including external crystals (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential inputs (5-710 MHz).
• Highly configurable output drivers support LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats with independent voltage levels.
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps resolution.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch/router and 1 GbE/10 GbE interfaces
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific factory programming code associated with the B05078 suffix against the official Skyworks Solutions ordering guide. Confirm that the QFN-24 package dimensions and thermal characteristics align with the target PCB land pattern requirements for the application environment.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Ensure the input reference signal matches the supported format and frequency range. Verify that the output driver voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the receiving device specifications.

Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. It replaces discrete crystal oscillators and frequency translators. The 'GMR' suffix indicates tape-and-reel packaging, while the 'B' prefix denotes custom factory programming via NVM.

Replacement Considerations

Consult the Skyworks Solutions cross-reference documentation for verified substitutes within the Si5338 series. Ensure replacement parts maintain compatibility with the existing I2C configuration and pinout if direct substitution is required.
