SI5338C-B04382-GM

Overview

The SI5338C-B04382-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent clocks with zero ppm precision from a single core supply of 1.8, 2.5, or 3.3 V. The device supports input frequencies up to 710 MHz and generates outputs ranging from 0.16 MHz to 710 MHz across LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. Key electrical parameters include a typical RMS jitter of 0.7 ps, a maximum output frequency of 710 MHz, and a maximum input frequency of 710 MHz. It operates within a temperature range of -40°C to +85°C in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Supports PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliance.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (up to 710 MHz).
• Independent output voltage per driver selectable at 1.5, 1.8, 2.5, or 3.3 V.

Applications

• Ethernet switch/router timing
• PCIe Gen1/2/3/4 clocking
• Processor and FPGA clocking
• Telecom line cards

Procurement Notes

Verify the specific B04382 suffix configuration against the official Skyworks ordering guide to ensure correct factory programming. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Check for current lifecycle status as availability may vary by region.

Selection Notes

Select this component when low-jitter (< 0.7 ps RMS) and high-precision frequency synthesis are required for multiple disparate clock domains. Ensure the target application utilizes I2C/SMBus interfaces for configuration via ClockBuilder Pro software. Verify that the required output signal formats (LVPECL, LVDS, etc.) align with the device's configurable driver capabilities.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and frequency translators. The 'C' designation typically indicates specific performance or packaging variants within the broader Si5338 series, while the alphanumeric suffix defines the pre-programmed frequency plan.

Replacement Considerations

Direct pin-compatible replacements within the same family include SI5338A-B-GM and SI5338N-B-GMR. These alternatives offer similar form factors but may differ in maximum output frequency specifications or specific jitter performance metrics. Verify register compatibility if migrating between variants.
