●Product Details
●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.
