SI53119-A01AGMR

Overview

The SI53119-A01AGMR 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 clock distribution in PCI Express systems. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports maximum input frequencies up to 150 MHz. Packaged in a QFN-72 form factor, it functions reliably across an industrial temperature range from -40°C to +85°C with a typical operating current of 25 mA.

Feature Summary

• 1:19 differential fanout configuration
• Zero-delay buffering capability
• QFN-72 surface mount package

Applications

• PCIe fanout applications
• Zero-delay buffer implementations

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted, with some sources indicating non-sale status in specific regions. Verification of current stock levels and alternative sourcing channels is required before procurement planning.

Selection Notes

Select this part for designs requiring a single differential input to drive nineteen differential loads. Ensure the design accommodates the 3.135 V to 3.465 V power supply requirement and the QFN-72 thermal characteristics. Confirm that the 150 MHz maximum input frequency meets system timing specifications.

Part Context

The SI53119 belongs to the Si53119 series of clock buffers. It is distinct from other Skyworks components like the SI53156 or SI53159 due to its specific 1:19 output count and PCIe-focused architecture.

Replacement Considerations

As the part is End-of-Life, no direct public substitute part numbers are confirmed in the provided documentation. Designers should consult official replacement guides or contact the manufacturer for qualified alternatives.
