The ADN8102 is a 4-channel Bidirectional CX4 equalizer that can equalize data from 1.875 GHz to 3.75 Gbps, with up to 22 dB of input gain to compensate for up to 30 meters of CX4 cable. It has low power consumption of 125 mW/channel and supports 8b10b, scrambled, or uncoded NRZ data, and provides an I2C control interface.
The ADN8102 is a quad bidirectional CX4 cable/backplane equalizer that provides eight differential PECL/CML‑compatible inputs and eight differential CML outputs. It offers programmable input equalization and output pre‑emphasis to compensate for cable loss, loss‑of‑signal detection, and loopback testing, making it suitable for 10GBase‑CX4, InfiniBand, Fibre Channel, XAUI, and Gigabit Ethernet applications.
Key specifications include a maximum NRZ data rate of 3.75 Gbps, programmable boost up to 22 dB at 1.875 GHz, low power consumption (125 mW/channel), and operation over a temperature range of –40 °C to +85 °C. The device is supplied in a 9 mm × 9 mm 64‑lead LFCSP package and can be controlled via toggle pins, an I²C interface, or a PC control interface.
