SI5338N-B05552-GM

Overview

The SI5338N-B05552-GM 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 LVDS, LVPECL, 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.

Feature Summary

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

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout configuration and factory programming settings. Ensure I2C pull-up voltages are compatible with the selected core supply voltage. Confirm package type matches the design footprint requirements.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single source. Verify that the target output format (LVDS, CMOS, etc.) aligns with the receiver specifications. Check if the required input frequency range falls within the supported limits for crystal or direct drive modes.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete oscillators and frequency translators in high-performance digital systems. The N suffix typically denotes a specific factory-programmed configuration variant within the broader Si5338 product line.

Replacement Considerations

Direct replacements must match the 24-QFN package and I2C interface. Verify functional compatibility with other Si5338 variants by comparing output driver configurations and supported frequency ranges in the datasheet.
