TOKENRINGNETWORKING
COMPONENTS
APPLICATION CIRCUIT
APPLICATION NOTES
• This Bel token ring networking component has been developed for use with the Texas Instruments C30 integrated
comm processor and transceiver and C60 transceiver only. 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.
