CY2DP814ZXI

Overview

The CY2DP814ZXI is a 1:4 clock fanout buffer manufactured by Infineon Technologies, originally developed by Cypress Semiconductor. It operates on a single 3.3 V supply and features a configurable differential input supporting LVDS, LVPECL, or LVTTL logic families. The device provides four differential LVPECL output pairs capable of driving 50-ohm loads. Key electrical specifications include a maximum operating frequency of 450 MHz, a typical propagation delay of 4 ns, and an output-to-output skew of 85 ps. It is housed in a 16-TSSOP surface-mount package.

Feature Summary

• Configurable single input receiver for LVDS, LVPECL, or LVTTL signals via the CONFIG pin
• Four differential LVPECL output pairs with 50-ohm load drive capability
• Low propagation delay (typical 4 ns) and low output skew (typical 85 ps)
• Commercial temperature range operation (-40°C to 85°C)

Applications

• Data communications clock management
• Level translation from single-ended inputs to LVPECL
• Distribution of LVDS-based clock signals

Procurement Notes

Verify component authenticity through authorized distributors or official Infineon channels. Confirm the specific ordering suffix 'ZXI' matches the required tube packaging and commercial temperature grade. Ensure compatibility with existing 3.3 V power rails and signal integrity requirements before procurement.

Selection Notes

Select this component when a low-skew, high-speed fanout buffer is required for distributing clock signals across multiple LVPECL destinations. The configurable input allows flexibility in interfacing with various source logic families. Ensure the design accommodates the 16-TSSOP package dimensions and thermal dissipation limits for the target application environment.

Part Context

This part belongs to the CY2DP series of network circuits produced using advanced CMOS technology. While originally branded under Cypress Semiconductor, the product line is now managed by Infineon Technologies. The CY2DP814 serves as a specialized solution for reducing loading on input clocks within complex digital systems.

Replacement Considerations

Check for updated revisions or equivalent parts within the Infineon portfolio if the CY2DP814ZXI is discontinued. Verify pin compatibility and electrical parameters against potential substitutes to ensure seamless integration without redesigning the PCB layout.
