SI53019-A05AGM

Overview

The SI53019-A05AGM is a clock buffer manufactured by Skyworks Solutions, Inc. It features six outputs and supports input frequencies up to 210 MHz with maximum output frequencies of 100 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V. It is housed in a QFN-32 package designed for surface mount installation. The component functions within an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides one-to-six fan-out buffering capability for clock signals
• Supports PCI Express Gen1/2/3 interface standards
• Operates with low voltage power supply requirements

Applications

• PCI Express system clock distribution
• Server and storage backplane timing
• High-speed digital interface synchronization

Procurement Notes

Verify the specific suffix configuration against official Skyworks documentation to ensure compatibility with target design requirements. Confirm that the QFN-32 package dimensions align with PCB footprint specifications. Check current availability status as manufacturing cycles may vary. Ensure moisture sensitivity handling procedures are followed during assembly to maintain component integrity.

Selection Notes

Select this component when a single reference clock requires distribution to multiple PCI Express compliant destinations. Evaluate the 100 MHz output frequency limit against system bandwidth needs. Consider the QFN-32 thermal performance for dense board layouts. Verify that the 3.3V nominal supply range matches the system power architecture without requiring additional level shifting.

Part Context

This part belongs to the SI53156 series family of clock buffers. It serves as a specialized solution for fan-out applications in high-speed serial link architectures. The device integrates buffering logic optimized for signal integrity in PCIe environments. It complements other Skyworks timing products by providing dedicated distribution stages.
