CY2PP326AI

Overview

The CY2PP326AI is a dual-input, six-output differential clock fanout buffer manufactured by Cypress Semiconductor Corp. Designed for high-speed signal distribution, it supports ECL and PECL input/output standards with a maximum operating frequency of 1.5 GHz. The device operates within two voltage ranges: 2.375V to 2.625V or 3.135V to 3.465V. It is housed in a 32-TQFP (7x7 mm) surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual 1:6 differential clock/data fanout buffer configuration
• Supports ECL and PECL input and output signaling standards
• Maximum operating frequency of 1.5 GHz
• Compatible with 2.5V and 3.3V supply voltages

Applications

• High-speed data communication systems requiring clock distribution
• Networking equipment utilizing PECL/ECL interfaces
• Industrial computing applications needing low-jitter clock buffering

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature grade. Ensure the selected variant matches the required 32-TQFP form factor and industrial temperature rating (-40°C to +85°C). Confirm supply voltage compatibility with the target system's 2.5V or 3.3V rails before integration.

Selection Notes

Select this component when a single source requires distribution to six differential loads using ECL or PECL logic levels. The 1.5 GHz bandwidth suits high-frequency clocking needs. Verify that the PCB layout accommodates the 7x7 mm 32-TQFP footprint and that the power supply design provides stable regulation within the specified 2.375V–2.625V or 3.135V–3.465V windows.

Part Context

This part belongs to the Cypress clock buffer and driver family, specifically designed for differential signal integrity. It serves as a replacement for legacy discrete transistor buffers in high-speed digital designs, offering integrated gain and impedance matching for ECL/PECL networks without external components.
