The ADN8102 is a quad bidirectional CX4 cable/backplane equalizer with eight differential PECL-/CML-compatible inputs with programmable equalization and eight differential CML outputs with programmable output levels and pre-emphasis or de-emphasis. The operation of this device is optimized for NRZ data at rates up to 3.75 Gbps.
The receive inputs provide programmable equalization to compensate for up to 30 meters of CX4 cable (24 AWG) or 40 inches of FR4, and programmable pre-emphasis to compensate for up to 15 meters of CX4 cable (24 AWG) or 40 inches of FR4 at 3.75 Gbps. Each channel also provides programmable loss-of-signal detection and loopback capability for system testing and debugging.
The ADN8102 is controlled through toggle pins, an I2C® control interface that provides more flexible control, or a combination of both. Every channel implements an asynchronous path supporting dc to 3.75 Gbps NRZ data, fully independent of other channels. The ADN8102 has low latency and very low channel-to-channel skew.
The main application for the ADN8102 is to support switching in chassis-to-chassis applications over CX4 or InfiniBand® cables.
The ADN8102 is packaged in a 9 mm × 9 mm 64-lead LFCSP (QFN) package and operates from −40°C to +85°C.Applications
