SI5338L-B06241-GM

Overview

The SI5338L-B06241-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 formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. The device operates with a core supply voltage of 1.8 V, 2.5 V, or 3.3 V and accepts input frequencies up to 710 MHz via differential inputs or up to 350 MHz via single-ended inputs. It features low phase jitter of 0.7 ps RMS typical, glitchless frequency adjustments, and spread spectrum capabilities.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with zero ppm precision.
• 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 (up to 710 MHz), HCSL (up to 250 MHz), and CMOS/SSTL/HSTL (up to 350 MHz).
• Features independent output voltage selection (1.5, 1.8, 2.5, or 3.3 V) and glitchless frequency/phase adjustment.

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 MSAN/DSLAM/PON equipment.

Procurement Notes

Verify the specific ordering suffix B06241 against the manufacturer's current documentation to confirm factory-programmed frequency and format configurations. Ensure compatibility with I2C/SMBus interface requirements for system integration. Check for moisture sensitivity levels and recommended reflow soldering profiles during assembly planning.

Selection Notes

Select this component when independent frequency synthesis across four outputs is required without crystal limitations. Verify that the target output signal formats (LVPECL, LVDS, etc.) and voltage levels match the load requirements. Confirm that the input reference source falls within the supported frequency ranges for the chosen pin configuration.
