SI53154-A11AGM

Overview

The SI53154-A11AGM is a clock buffer manufactured by Skyworks Solutions, Inc., designed for high-speed serial interface applications. It functions as a 1:4 fanout buffer supporting PCIe Gen 1 through Gen 5 standards. The device operates with a maximum output frequency of 100 MHz and accepts input frequencies up to 210 MHz. It requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a QFN-24 package and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports PCIe Gen 1/2/3/4/5 interfaces
• Provides 1:4 fanout buffering capability
• Maximum output frequency of 100 MHz
• Operates within a 3.135 V to 3.465 V supply range

Applications

• PCI Express system clock distribution
• High-speed data acquisition systems
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix 'A11' against official Skyworks documentation to confirm pinout and configuration differences compared to other variants like A01. Ensure compliance with RoHS directives and moisture sensitivity levels prior to assembly. Confirm availability status directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when a low-jitter 1:4 fanout solution is required for PCIe Gen 1 to Gen 5 links. Ensure the design accommodates the 3.3V nominal supply constraints and the QFN-24 thermal requirements. Verify that the input source frequency does not exceed the 210 MHz maximum limit for proper operation.

Part Context

This part belongs to the SI53154 series of precision clock buffers. It serves as a successor or alternative to older differential buffer solutions like the CY28400OC, offering support for newer PCIe generations. The series is widely used in server and storage architectures requiring robust clock distribution.

Replacement Considerations

The CY28400OC is identified as a potential replacement or previous generation equivalent for similar 100 MHz differential buffering tasks, though it lacks Gen 4/5 support.
