SI5338L-B04837-GM

Overview

The SI5338L-B04837-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 with frequencies up to 710 MHz. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and features independently configurable output voltages (1.5 V, 1.8 V, 2.5 V, or 3.3 V). Key electrical parameters include a typical RMS jitter of 0.7 ps, a maximum input frequency of 710 MHz, and a maximum output frequency of 710 MHz. It is housed in a 24-lead QFN package.

Feature Summary

• I2C-programmable synthesis with 0 ppm precision using patented MultiSynth technology
• Four independent output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats
• Low phase jitter performance with a typical RMS value of 0.7 ps
• Flexible input reference options including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm factory programming details. Confirm that the I2C pull-up voltage requirements align with the system design, particularly if operating below 2.5 V. Ensure ESD protection measures are implemented during handling due to the device's sensitivity.

Selection Notes

Select this component for designs requiring low-jitter, any-frequency synthesis across multiple domains. Verify that the required output signal formats and voltage levels are supported by the independent driver supplies. Check thermal characteristics, specifically the junction-to-ambient resistance, to ensure adequate heat dissipation within the 4x4 mm QFN package under maximum load conditions.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The 'L' suffix typically denotes a specific factory-programmed configuration variant within the series. The device replaces multiple discrete oscillators, reducing board space and power consumption while providing precise frequency generation capabilities.

Replacement Considerations

Direct pin-compatible replacements within the same family may exist but require verification of the specific frequency and format configurations. Consult the official datasheet for alternative part numbers with matching electrical specifications and package dimensions.
