SI5338N-B06180-GMR

Overview

The SI5338N-B06180-GMR is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis on four 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 low phase jitter of 0.7 ps RMS typical. Configuration is managed via an I²C/SMBus interface, allowing for flexible input references including crystals, CMOS, and differential signals up to 710 MHz.

Feature Summary

• MultiSynth™ technology enables zero ppm precision and independent any-frequency synthesis on four outputs.
• Supports diverse output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• Low phase jitter performance of 0.7 ps RMS typical.
• Flexible input options: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential (5–710 MHz).

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 compatibility with the intended I²C bus voltage levels and check for moisture sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when independent clock generation with varying frequencies and signal formats is required on a single IC. Consider the 4x4 mm QFN-24 package for space-constrained designs. Validate that the required output frequencies fall within the supported ranges for the chosen driver format, particularly noting limits for high-speed differential outputs versus single-ended CMOS.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The 'N' in the part number typically denotes a specific factory-programmed configuration or pinout variant within the broader Si5338 series, which shares core functionality but may differ in default settings or hardware configurations.

Replacement Considerations

Direct replacements within the same family include other Si5338 variants such as SI5338F-B-GMR or SI5338Q-B-GMR, provided their factory-programmed parameters match the design requirements. Verify pin-to-pin compatibility and electrical specifications before substitution.
