SI5338K-B06098-GM

Overview

The SI5338K-B06098-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Maximum input frequency reaches 710 MHz via differential inputs, while outputs support up to 710 MHz for LVPECL/LVDS/CML. Core supply voltage ranges from 1.71 V to 3.63 V (1.8 V, 2.5 V, or 3.3 V nominal). Typical operating current is 45 mA. Jitter performance is 0.7 ps RMS typical. It operates within -40 °C to +85 °C in a 24-lead QFN package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential (5–710 MHz).
• Configurable output drivers support LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats with independent voltage levels (1.5, 1.8, 2.5, or 3.3 V).
• Features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps resolution.

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant timing.
• Ethernet switch/router and 1 GbE/10 GbE interfaces.
• Processor and FPGA clocking systems.
• Broadcast video/audio timing distribution.
• Telecom line cards and Fibre Channel/SAN applications.

Procurement Notes

Verify the specific ordering suffix B06098 against the manufacturer's official documentation to confirm the exact pre-programmed frequency plan and output configuration. Ensure I2C pull-up voltages are compatible with the selected core supply voltage. Check humidity sensitivity handling requirements during assembly.

Selection Notes

Select this component when low jitter (<1 ps RMS) and high flexibility are required for multiple clock domains. Verify that the required output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Confirm input reference availability matches the supported frequency bands.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators by providing four independent clock outputs from a single reference source. The device integrates PLL and MultiSynth stages for precise frequency synthesis.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications if considering alternative clock generators from other manufacturers.

FAQ
