SI5338C-B05692-GMR

Overview

The SI5338C-B05692-GMR 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 outputs with frequencies up to 710 MHz. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. It includes flexible input references, spread spectrum capabilities, and I2C/SMBus programming via ClockBuilder Pro software.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports diverse output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL with independent voltage levels (1.5V, 1.8V, 2.5V, 3.3V).
• Low phase jitter performance of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock standards.
• Configurable spread spectrum (SSC) on any output with frequency deviation from 0.5% to 5.0%.

Applications

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

Procurement Notes

Verify the specific factory configuration encoded in the ordering suffix B05692 against the target design requirements using the official datasheet. Confirm that the 24-QFN package dimensions and thermal characteristics align with the PCB land pattern specifications provided in the document.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single IC. Ensure the input reference source matches the supported ranges (e.g., differential up to 710 MHz or crystal 8-30 MHz). Verify that the required output signal formats and voltage levels are compatible with the Si5338's configurable driver options.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'C' indicates a specific temperature or grade variant, while 'B05692' defines the pre-programmed frequency and format configuration stored in the internal NVM. The '-GMR' suffix denotes the tape-and-reel packaging format for surface-mount assembly.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory configurations (e.g., SI5338A, SI5338Q). When substituting, ensure the new part's programmed frequencies and output formats match the original design, as the base silicon remains identical.
