11.6.2 LED driver signals

Fault and Active LED signals are located in the FC-SCA connector (J1). See Table 30 for the output characteristics of the

LED drive signals.

11.6.3 FC Differential output

The serial output signal voltage characteristics are provided in Table 31. The outputs are not AC coupled in order to deliver

maximum signal without rise and fall time degradation. You must AC couple the receiver to isolate potentially different DC

characteristics of the outputs and the receiver.

Figure 16 provides the data output valid eye diagram relative to the bit cell time.
