SI5338C-B04398-GMR

Overview

The SI5338C-B04398-GMR is a programmable 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 LVDS, LVPECL, 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 inputs up to 710 MHz differentially or 200 MHz single-ended. It features low phase jitter (0.7 ps RMS typ), glitchless frequency adjustment via I2C/SMBus, and spread spectrum capabilities within a 24-lead QFN package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four outputs with zero ppm precision.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), and differential signals (up to 710 MHz).
• Configurable output drivers support LVDS, LVPECL, CML, HCSL, CMOS, SSTL, and HSTL formats.
• Glitchless frequency adjustments in 1 ppm steps and independent phase offset control (< 20 ps accuracy).

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 solutions.
• Broadcast video/audio timing distribution.

Procurement Notes

Verify the specific ordering suffix B04398 against the manufacturer's current documentation to confirm factory-programmed frequency and format configurations. Confirm RoHS compliance status and moisture sensitivity level requirements for the intended assembly process.

Selection Notes

Select this component when independent frequency synthesis across multiple domains is required without using discrete oscillators. Ensure the target application utilizes compatible input frequencies and that the required output voltage levels (1.5 V to 3.3 V) match the load specifications.

Part Context

This part belongs to the Si5338 family of quad clock generators. The 'C' designation typically indicates specific output driver configurations or performance grades compared to other variants like 'A' or 'Q'. The 'GMR' suffix denotes tape-and-reel packaging suitable for automated surface-mount assembly.

Replacement Considerations

Direct pin-compatible replacements within the same family include SI5338A-B-GMR or SI5338Q-B-GMR, provided their specific electrical characteristics and pre-programmed parameters align with the design requirements.
