SI5338L-B06240-GM

Overview

The SI5338L-B06240-GM is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical, independent output voltage configurations (1.5V, 1.8V, 2.5V, or 3.3V), and I2C/SMBus programming. It operates on a single core supply of 1.8V, 2.5V, or 3.3V within an ambient temperature range of -40°C to +85°C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Low phase jitter of 0.7 ps RMS typical for high-precision timing applications.
• Highly-configurable output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.
• I2C/SMBus compatible interface for easy configuration using ClockBuilder Pro software.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'B06240' against the manufacturer's current datasheet to confirm factory-programmed NVM content and pinout compatibility. Ensure the QFN-24 package land pattern matches the recommended PCB layout specifications provided in the official documentation.

Selection Notes

Select this component when independent frequency synthesis across four outputs is required with minimal jitter. Confirm that the input reference frequency (crystal or external clock) falls within the supported ranges: 8–30 MHz for crystals, up to 200 MHz for CMOS, and up to 710 MHz for differential inputs.

Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. The 'L' suffix typically denotes a specific factory-programmed variant within the series, while 'GM' indicates the 24-lead QFN package. It serves as a replacement for multiple discrete oscillators in complex digital systems.

Replacement Considerations

Direct replacements must match the 24-QFN package and support similar output formats. Verify if alternative Skyworks models like the SI5338A or SI5338B offer compatible electrical characteristics and pinouts for the specific application requirements.
