APPLICATION NOTES
APPLICATION CIRCUIT
960003B
Refer to Bel short form catalog for list of recommended AMD transceivers compatible for use with these parts.
Resistor values are chosen to precision match the impedance characteristics of the AMD transceiver with that of the
internal filter network within magnetics module.
This part provides impedance matching, signal wave shaping, EMI and common mode noise suppression and high
voltage isolation.
