SI5338K-B06029-GM

Overview

The SI5338K-B06029-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates with a core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Input references range from external crystals (8–30 MHz) to differential inputs up to 710 MHz. Configuration is managed via an I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm precision.
• Supports highly 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).
• 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.
• Features independent frequency increment/decrement for glitchless adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy.

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 revision to confirm pinout compatibility and factory-programmed NVM content. Ensure the I²C pull-up voltage matches the system bus requirements, as register configuration may be necessary for voltages below 2.5 V. Confirm package availability and moisture sensitivity level handling procedures prior to assembly.

Selection Notes

Select this component when designing systems requiring flexible clock synthesis with low jitter across multiple output domains. Ensure the input reference source matches the supported frequency ranges (e.g., differential up to 710 MHz). Verify that the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) are compatible with the target load devices. Use ClockBuilder Pro software for optimal configuration and jitter validation.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The 'K' suffix typically denotes specific output enable control configurations or pin assignments within the family. The 'GM' indicates a tape-and-reel packaging format suitable for automated surface-mount assembly. The device replaces multiple discrete oscillators, reducing board space and power consumption.

Replacement Considerations

Direct replacements within the Si5338 family require verification of the specific ordering suffix to ensure identical pinout and programmed parameters. Cross-model substitution with Si533x series devices requires careful review of electrical specifications, particularly output drive capabilities and jitter performance, to ensure system compliance.
