Functional Description
The SFP-MADI-COAX transceiver is a Small Form Factor Pluggable (SFP) module with coaxial interface. HD-
BNC connectors are used to interface the module with 75  coaxial cables.
The SFP-MADI-COAX transceiver contains both a cable driver for transmission of the MADI signal, and an
automatic cable equalizer of reception of a MADI signal.
Module Installation
The module is simply inserted, small end first, under manual pressure. Controlled hot plugging is ensured by
design. The module housing makes initial contact with the router board EMI shield, mitigating potential damage
due to Electrostatic Discharge (ESD).
Technical Specifications
Note that specifications are subject to change without notice.
Absolute Maximum Ratings
Exceeding any of these ratings may permanently damage the module. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
