APPLICATION NOTES
APPLICATION CIRCUIT
TOKEN RING NETWORKING
COMPONENTS
ˇ Bel has created these products for use with token ring 4/16 Mbps chipsets developed by Texas Instruments in 150 ohm
STP and 100 ohm UTP media applications; however, both the 150 ohm and 100 ohm connections cannot be used
simultaneously. The Bel modules provide internal filter networks on the transmit channels, in addition to both transmit
and receive high voltage isolation transformers, plus common mode chokes on both channels for EMI and noise
suppression.
ˇ 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.
