SI53119-A03AGMR

Overview

The SI53119-A03AGMR is a 1:19 low-power HCSL differential clock buffer manufactured by Skyworks Solutions Inc. It provides one input and nineteen outputs, supporting maximum frequencies up to 1.417 GHz. The device operates on a single supply voltage ranging from 1.71 V to 3.63 V. It is housed in a QFN-36 package and functions within an operating temperature range of -40°C to +85°C. This component serves as a jitter attenuating clock generator and buffer for high-speed digital applications.

Feature Summary

• Integrates all external resistors to reduce board space and material costs
• Supports 85 Ohm transmission lines for optimized signal integrity
• Provides low-power HCSL differential output buffering

Applications

• Intel DB1200ZL specification compliant systems
• PCI Express (PCIe) clock distribution networks
• High-performance server and storage backplanes

Procurement Notes

Verify the specific suffix A03 against the official Skyworks datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the QFN-36 package thermal pad soldering process aligns with your manufacturing capabilities. Cross-reference the RoHS status and lead-free compliance with current environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a single clock source requires distribution to nineteen distinct loads with minimal power consumption. It is suitable for designs requiring strict adherence to Intel DB1200ZL specifications. Consider the QFN-36 footprint constraints and the need for integrated termination resistors when evaluating alternative buffer solutions for high-density PCB layouts.

Part Context

This part belongs to the SI53119 series of clock buffers designed for demanding high-speed interfaces. It complements other Skyworks timing solutions by offering high fan-out capabilities while maintaining low power dissipation. The series targets applications requiring precise clock distribution across multiple components in complex electronic systems.

Replacement Considerations

Consult the official Skyworks replacement guide for direct substitutes. Verify compatibility regarding output drive strength, supply voltage ranges, and package dimensions before swapping components in existing designs.
