1. Refer to
2. Refer to
3. Refer to fiber transceiver manufacturers recommendations for termination circuitry. Suitable fiber transceivers include:
4. Bypassing to chassis ground (if available) provides additional EMI shielding.
5. If the fiber interface is not used, FIBIN, FIBIP, FIBON, and FIBOP may be left unconnected.
6. Placement of this cap should be verified for each application. This cap typically reduces error rates at long line lengths but
7. If bit 17.3 = 0, series terminations resistors are recommended for all MII outputs. The proper value is application specific.
Figure 21. Typical Interface Circuitry

HFBR-5103 and HFBR-5105.
is implementation specific.
If bit 17.3 = 1, termination resistors are not required.
