SI5338N-B06108-GM

Overview

The SI5338N-B06108-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 single core supply of 1.8 V, 2.5 V, or 3.3 V with individual output voltages configurable to 1.5 V, 1.8 V, 2.5 V, or 3.3 V. It features low phase jitter of 0.7 ps RMS typical, zero ppm frequency accuracy, and I2C/SMBus programming via ClockBuilder Pro software.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Configurable outputs support LVPECL/LVDS up to 710 MHz, HCSL up to 250 MHz, and CMOS up to 200 MHz.
• Features independent glitchless frequency adjustments in 1 ppm steps and phase adjustment with <20 ps accuracy.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm factory configuration parameters. Ensure compatibility with the required I2C pull-up voltage levels if operating below 2.5 V. Confirm package availability and moisture sensitivity handling requirements prior to assembly.

Selection Notes

Select this component for designs requiring independent frequency generation across multiple domains without external oscillators. Ensure the target output format (LVDS, LVPECL, etc.) falls within the specified frequency limits. Verify that the system power budget accommodates the typical 45 mA core supply current plus output driver loads.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators by providing synthesized clocks with low jitter. The device integrates an internal PLL and MultiSynth dividers to generate precise frequencies from various reference inputs.

Replacement Considerations

Direct pin-to-pin replacements within the Si5338 family may exist but require verification of specific output configurations and jitter performance. Consult the official datasheet for compatible variants with similar package footprints and electrical characteristics.
