SI5338C-B05917-GM

Overview

The SI5338C-B05917-GM 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, CML, 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. Configuration is managed via an I2C/SMBus interface.

Feature Summary

• Four independent output drivers supporting any frequency synthesis with 0 ppm precision
• Flexible input references including external crystals (8-30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz
• Configurable output formats: LVPECL/LVDS (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), and SSTL/HSTL (up to 350 MHz)
• Independent frequency increment/decrement and phase adjustment capabilities for glitchless adjustments

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliance
• Ethernet switch/router timing
• Processor and FPGA clocking
• Telecom line cards and MSAN/DSLAM/PON systems
• Fibre Channel and SAN applications

Procurement Notes

Verify the specific suffix 'B05917' against the manufacturer's ordering guide to confirm factory programming details. Ensure the QFN-24 package handling meets moisture sensitivity level requirements during assembly. Confirm that the I2C pull-up voltage aligns with the supported range of 1.71 V to 3.63 V for proper communication.

Selection Notes

Select this component when replacing multiple crystal oscillators with a single programmable source. Ensure the required output frequencies fall within the specified limits for the chosen signal format (e.g., LVDS up to 710 MHz vs. CMOS up to 200 MHz). Verify that the input reference source matches the supported types, such as differential inputs up to 710 MHz or single-ended CMOS up to 200 MHz.

Part Context

This part belongs to the Si5338 family of low-jitter clock generators. The 'C' variant typically denotes specific performance or configuration tiers within the series. The 'GM' suffix indicates a lead-free, halogen-free RoHS-compliant product in a 24-lead QFN package. Programming is facilitated using Skyworks ClockBuilder Pro software.

Replacement Considerations

Direct pin-to-pin replacements within the Si5338 family may require reprogramming via ClockBuilder Pro if output configurations differ. Verify that alternative parts support the same output formats and frequency ranges required by the design.
