CY2DP3110AI

Overview

The CY2DP3110AI is a differential clock and data fanout buffer manufactured by Cypress Semiconductor Corp. It provides a 2:10 distribution ratio, accepting two differential inputs to drive ten differential outputs. The device supports ECL and PECL input/output standards and operates at a maximum frequency of 1.5 GHz. It requires dual power supplies ranging from 2.375V to 2.625V or 3.135V to 3.465V. Packaged in a 32-TQFP (7x7 mm) surface-mount case, it functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• 2:10 differential clock/data fanout buffer configuration
• Supports ECL and PECL input and output standards
• Maximum operating frequency of 1.5 GHz
• Dual voltage supply options: 2.5V nominal or 3.3V nominal

Applications

• High-speed clock distribution networks
• Data communication systems requiring low skew buffering
• Industrial control systems with differential signaling requirements

Procurement Notes

Verify the specific ordering suffix against official Cypress documentation to confirm package type and temperature grade. Ensure the supplier provides genuine components matching the 32-TQFP specification. Confirm that the voltage supply rails align with the device's specified 2.5V or 3.3V operational ranges before integration.

Selection Notes

Select this component when a single differential source must drive multiple downstream loads with minimal skew. Verify that the system logic levels match the supported ECL or PECL standards. Ensure the PCB layout accommodates the 32-LQFP footprint and that the power supply design meets the specified voltage tolerances for stable high-frequency operation.

Part Context

This part belongs to the CY2DP series of differential clock buffers designed for high-performance timing applications. Cypress Semiconductor developed these devices to provide precise signal distribution in complex digital systems. The CY2DP3110AI specifically addresses scenarios requiring robust differential buffering with wide frequency capabilities.

Replacement Considerations

Check for direct substitutes within the CY2DP family, such as the CY2DP3120, which offers a different input-to-output ratio. Verify pin compatibility and electrical specifications before substituting any alternative buffer IC.
