SI5338N-B05025-GMR

Overview

The SI5338N-B05025-GMR is a programmable quad clock generator from Skyworks Solutions. It synthesizes four independent output clocks with zero ppm frequency accuracy using MultiSynth technology. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. Maximum input frequency reaches 710 MHz via differential inputs, while outputs support up to 710 MHz for differential and 200 MHz for CMOS. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with typical current consumption of 45 mA. Jitter performance is characterized by 0.7 ps RMS random jitter.

Feature Summary

• MultiSynth technology enables any-frequency synthesis with 0 ppm precision on four independent drivers
• Flexible output configurations supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL signal formats
• Low phase jitter of 0.7 ps RMS typical with glitchless frequency adjustment capabilities
• I2C/SMBus compatible programming interface with spread spectrum generation

Applications

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

Procurement Notes

Verify the specific ordering suffix B05025 against the manufacturer's official documentation to confirm the exact pin assignment and configuration parameters. Ensure the I2C pull-up voltage requirements are met if operating below 2.5 V. Confirm package type matches the 24-QFN specification.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single source. Verify that the target output signal format (LVDS, LVPECL, etc.) and frequency range fall within the specified limits. Check power supply constraints to ensure compatibility with the 1.8 V, 2.5 V, or 3.3 V core supply options.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The family utilizes patented MultiSynth architecture to replace multiple discrete oscillators. Variations in the suffix typically denote different factory-programmed configurations or pin assignments rather than changes in core functionality.

Replacement Considerations

Consult the manufacturer's cross-reference data for verified substitutes. Generic replacements may not support the same MultiSynth flexibility or jitter specifications.
