SI5338N-B06173-GMR

Overview

The SI5338N-B06173-GMR 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 differential and single-ended outputs including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V, with individual output supplies configurable between 1.5 V and 3.3 V. Key electrical parameters include a maximum input frequency of 710 MHz, typical phase jitter of 0.7 ps RMS, and an operating temperature range of –40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Flexible input reference options: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), or differential (5–710 MHz).
• Low phase jitter performance of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards.
• Independent output voltage per driver (1.5, 1.8, 2.5, or 3.3 V) and glitchless frequency adjustments in 1 ppm steps.

Applications

• PCIe Gen 1/2/3/4 systems
• Ethernet switch/router clocking
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout configuration and factory programming settings. Ensure compatibility with I2C/SMBus interface requirements for system integration. Confirm package type is 24-lead QFN (4x4 mm) and check moisture sensitivity levels for handling procedures.

Selection Notes

Select this component when low jitter (<1 ps RMS) and flexible output formats are required for high-speed interfaces like PCIe or Ethernet. Ensure the design supports independent output supply voltages if mixing signal standards such as LVDS and CMOS. Verify that the input reference source matches one of the supported types (crystal, CMOS, or differential) within the specified frequency ranges.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'N' suffix typically denotes a specific factory-programmed configuration variant within the series. The device replaces multiple discrete oscillators, reducing board space and power consumption while providing precise clock distribution for complex digital systems.

Replacement Considerations

Direct replacements within the Si5338 family require matching the factory-programmed frequency and format configuration. Generic Si5338 devices can be used if field-programmable via ClockBuilder Pro software. Verify pin-to-pin compatibility and ensure the replacement supports the required output voltage levels and jitter specifications.
