SI53019-A05AGMR

Overview

The SI53019-A05AGMR is a clock buffer manufactured by Skyworks Solutions Inc., designed for high-speed digital applications. It operates within a supply voltage range of 3.135 V to 3.465 V, with a typical operating current of 85 mA. The device supports a maximum output frequency of 133.33 MHz and accepts an input clock signal. It features HCSL output format and utilizes a 72-QFN (10x10 mm) package. The component is rated for operation between -40°C and +85°C, ensuring reliability in demanding environments.

Feature Summary

• Provides clock buffering functionality for high-speed serial interfaces
• Supports HCSL output signaling standards
• Operates with a single power supply voltage
• Designed for Intel QPI and PCIe applications

Applications

• Intel QuickPath Interconnect (QPI) systems
• PCI Express (PCIe) interface circuits
• High-speed data transmission backplanes

Procurement Notes

Verify the specific ordering suffix AGMR against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure the intended application matches the supported output format and voltage requirements. Cross-reference the part number with official Skyworks documentation to confirm current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when a dedicated clock buffer is required for Intel QPI or PCIe architectures. The HCSL output format dictates compatibility with downstream receivers supporting that standard. Consider the 72-QFN package dimensions for PCB layout constraints. Verify that the input clock frequency does not exceed the specified maximum limit of 133.33 MHz for proper operation.

Part Context

This part belongs to the Skyworks clock buffer family, distinct from their oscillators and generators. It serves as a passive distribution element rather than a frequency synthesizer. The model number indicates a specific pinout and electrical characteristic set tailored for server and storage infrastructure markets requiring low jitter clock distribution.
