SI5338C-B10105-GM

Overview

The SI5338C-B10105-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, 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. It accepts flexible input references up to 710 MHz and provides low phase jitter of 0.7 ps RMS typ. Configuration is performed via an I2C/SMBus interface.

Feature Summary

• Four independent output drivers supporting any frequency synthesis with 0 ppm precision
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), or differential (5-710 MHz)
• Independent output voltage configuration per driver at 1.5, 1.8, 2.5, or 3.3 V

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON applications

Procurement Notes

Verify the specific ordering suffix B10105 against the manufacturer's official documentation to confirm the exact pre-programmed frequency and output format configuration. Ensure compatibility with the required I2C address and signal levels before procurement.

Selection Notes

Select this component when replacing multiple fixed-frequency oscillators with a single programmable source. Verify that the required output frequencies fall within the supported ranges for the chosen output format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Confirm power supply requirements match the available system rails.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It is housed in a space-saving 4 x 4 mm, 24-lead QFN package. The device is designed to replace up to four different frequency crystal oscillators or operate as a frequency translator in high-performance timing applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When replacing existing oscillators, ensure the new part's pinout and electrical characteristics match the design requirements.
