The MAX3801 is a +3.3V adaptive cable equalizer designed for coaxial and twin-axial cable point-to-point communications applications. The equalizer includes differential CML data inputs and outputs, a loss-of-sig- nal (LOS) output, and a cable integrity monitor (CIM) output.
The MAX3801 adaptive cable equalizer accepts differential CML inputs and outputs, a loss‑of‑signal (LOS) indicator, and a cable integrity monitor (CIM). It operates from a single +3.3 V supply, consumes only 125 mW, and automatically adjusts to up to 30 dB of skin‑effect loss at 1.6 GHz, extending usable cable length for high‑frequency interconnects.
Typical applications include high‑speed links in communications and data systems, backplane and interconnect designs, and SDH/SONET transmission equipment. The device is offered in a 24‑pin QFN package and includes on‑chip terminations, low external component count, and a wide operating temperature range of 0 °C to +85 °C.
