ADN8102ACPZ

Overview

The ADN8102ACPZ 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 8b10b, scrambled, or uncoded NRZ data within an operating temperature range of −40°C to +85°C.

Feature Summary

• Provides programmable input equalization to compensate for channel loss in cables and backplanes.
• Features programmable output pre-emphasis and de-emphasis for signal integrity optimization.
• Supports per-lane positive/negative pair inversion to simplify routing requirements.
• Integrates loss-of-signal detection and loopback capabilities for system testing.

Applications

• 10GBase-CX4 interconnects
• InfiniBand chassis-to-chassis links
• XAUI interfaces
• Fibre Channel connections

Procurement Notes

Verify the specific suffix ACPZ-R7 against the manufacturer's current ordering guide to confirm package type and reel specifications. Ensure the design accounts for the required I2C address settings via ADDR pins. Confirm that the power supply sequencing meets the absolute maximum ratings to prevent damage during startup.

Selection Notes

Select this component when designing systems requiring bidirectional equalization for CX4 or InfiniBand standards. It is suitable for applications needing compensation for significant trace or cable attenuation at 3.75 Gbps. Consider the I2C interface if complex per-channel tuning is required over simple pin control.
