APPLICATION NOTES
APPLICATION CIRCUIT
TOKEN RING NETWORKING
COMPONENTS
Bel has developed this product for use with token ring 4/16 Mbps transceivers in 150 ohm STP and 100 ohm UTP
media applications; however, both the 150 ohm and 100 ohm connections cannot be simultaneous. The Bel module
provides isolation and impedance matching transformers plus common mode choke for either a transmit or receive
channel. External filtering is required.
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.
Bel's low profile, surface mount packaging is ideal for high speed pick and place machinery. Parts can be shipped on
tape and reel for high speed placement. Construction processes have been implemented for thermal compatibility
with high temperature IR reflow assembly processing. Post dipping of leads assist with PC board solderability. Each
part is optically inspected to meet rigid coplanarity requirements.
