SI53119-A01AGM

Overview

The SI53119-A01AGM is a PCIe fanout and zero-delay buffer manufactured by Skyworks Solutions. It features one differential input and nineteen differential outputs, designed for high-speed data transmission applications. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports a maximum input frequency of 150 MHz. It is housed in a QFN-72 package and functions reliably across an operating temperature range from -40°C to +85°C. The component draws a typical operating current of 25 mA.

Feature Summary

• 1:19 PCIe Fanout/Zero-Delay Buffer configuration
• Differential input and output signal types
• Maximum input frequency of 150 MHz
• QFN-72 surface-mount package

Applications

• PCIe system clock distribution
• High-speed digital interface buffering
• Server and storage backplane designs

Procurement Notes

The SI53119-A01AGM is listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, with some distributors indicating no stock or limited supply in specific regions. Verification of current lifecycle status and alternative sourcing channels is required before procurement planning.

Selection Notes

Select this component when a single differential clock source must drive up to nineteen differential loads with minimal skew. Ensure the design accommodates the 3.3V nominal supply voltage and the thermal requirements of the QFN-72 package. Verify that the 150 MHz maximum input frequency meets the system's clocking needs.

Part Context

This part belongs to the Si53119 series of clock buffers. It is distinct from other Skyworks clock generators and differentiators by its specific 1:19 fanout ratio and zero-delay buffer functionality tailored for PCIe architectures.

Replacement Considerations

Due to the EOL status, direct substitutes should be identified through official Skyworks obsolescence notices or verified cross-reference databases. No public substitute part numbers are confirmed in the provided documentation.
