This Bel module provides signal shaping and high voltage isolation, impedance matching, and EMI and noise suppression for both transmit and receive channels. This module can be used in either 150 ohm STP or 100 ohm UTP cable environments. * Suppression of board induced noise can be achieved with precision layout instructions, along with careful consideration of the selection and placement of discrete components for the interface circuit. * Do not connect both UTP and STP simultaneously. Only one media connection can be supported at any one time. * Additional common mode chokes are available for further suppression of unwanted signals.
