ADN8102ACPZ-R7

Overview

The ADN8102ACPZ-R7 is a quad, bidirectional CX4 equalizer designed for data rates up to 3.75 Gbps. It features eight differential CML-compatible inputs with programmable input equalization and eight differential CML outputs with programmable pre-emphasis. The device compensates for signal loss in up to 30 meters of CX4 cable or 40 inches of FR4 backplane at maximum speed. It operates on a flexible core supply ranging from 1.8 V to 3.3 V and includes an I2C control interface for configuration. Packaged in a 64-lead LFCSP (QFN), it supports NRZ data formats including 8b10b and scrambled codes.

Feature Summary

• Programmable input equalization providing up to 22 dB boost to compensate for channel loss
• Programmable output pre-emphasis/de-emphasis with up to 12 dB boost capability
• Flexible power supply operation supporting both 1.8 V and 3.3 V core voltages
• Integrated I2C control interface for detailed register-based configuration

Applications

• 10GBase-CX4 interconnects
• InfiniBand chassis-to-chassis connections
• XAUI and HiGig applications
• Fibre Channel systems operating at 1x and 2x speeds
• Gigabit Ethernet over backplanes or cables

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required packaging options. Confirm that the component meets all necessary environmental standards and regulatory requirements for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring bidirectional signal restoration for CX4 or InfiniBand links. Ensure the design accommodates the 64-lead LFCSP package dimensions and thermal requirements. Verify that the system logic levels are compatible with the specified 1.8 V to 3.3 V operating range and that I2C bus timing constraints are met.
