SI5338C-B01917-GMR

Overview

The SI5338C-B01917-GMR is a programmable quad clock generator 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 from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current 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

• I2C/SMBus programmable interface for flexible configuration
• Independent glitchless frequency adjustment in 1 ppm steps
• Supports spread spectrum modulation (0.5% to 5.0%)
• Compliant with PCIe Gen 1/2/3/4 Common Clock standards

Applications

• Ethernet switch/router timing
• PCIe Gen1/2/3/4 systems
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, tape-and-reel specifications, and environmental compliance status prior to procurement.

Selection Notes

Select this component when zero-ppm frequency accuracy and low jitter are required across multiple outputs. Ensure the target application voltage matches the supported 1.8 V, 2.5 V, or 3.3 V core supply options.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators by providing independent frequency synthesis on four channels within a compact 4x4 mm QFN package.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Generic replacements may not support the same MultiSynth architecture or jitter performance metrics.
