Magnetic Modules
For best performance, proper magnetic modules must be used with the VSC8201. In addition, some companies integrate the magnetic
modules into the RJ-45 connector.
Note on Return-Loss Compensation Circuit: Testing has indicated that some magnetic modules may not pass the IEEE specification
for return loss. In these cases, an extra resistor-capacitor circuit can be added for each of the sub-channels. See “Return Loss Circuit for
Pulse H5008 Transformer” on page 18. The presence of this circuit serves only to allow the system to pass IEEE return loss measure-
ments and does not affect the performance of the PHY in any other way. The exact values required for the resistors and capacitors var-
ies according to each manufacturer and can be found in Table 8: “Recommended Magnetic Modules.”
