Unused 100Base-FX interface
Figure B-11 shows the wiring of an unused „Fiber Optic Transceiver“. The interface uses PECL lines.
If a 100Base-FX interface is not used, the pins Px_TD_OUT_P and Px_TD_OUT_N can remain open (no Pull-Up or Pull-Down resistor necessary).
All other signals should be connected to GND level.
