SI5338K-B05616-GM

Overview

The SI5338K-B05616-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. It supports input frequencies up to 710 MHz and provides low phase jitter of 0.7 ps RMS typical. The device operates from a single core supply of 1.8, 2.5, or 3.3 V and features independently configurable outputs supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. Configuration is managed via an I2C/SMBus interface.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers
• Low phase jitter of 0.7 ps RMS typical
• Flexible input reference options including external crystal (8-30 MHz), CMOS (5-200 MHz), and differential inputs (up to 710 MHz)
• Independent output voltage per driver: 1.5, 1.8, 2.5, or 3.3 V

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant timing
• Ethernet switch/router clocking
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and shipping configuration. Ensure compatibility with the required I2C bus voltage levels for system integration. Confirm that the selected part number matches the exact frequency plan and output format requirements defined in the design specifications.

Selection Notes

Select this component when high-precision, glitchless frequency adjustments are required across multiple outputs. The device supports spread spectrum modulation on any output and independent phase adjustment with less than 20 ps steps. Consider the thermal characteristics and power consumption if operating at maximum frequency and load conditions within the -40 to +85 °C range.

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. The 'K' suffix typically denotes specific pin control configurations or output enable logic variations within the family. The '-GM' suffix indicates the QFN-24 package variant.

Replacement Considerations

Direct replacements must match the Si5338 family architecture and I2C programming interface. Verify that alternative parts support the same input frequency ranges and output drive capabilities. Consult the manufacturer's cross-reference guide for confirmed substitutes.
