• Table 4 describes the performance of the transmitter portion of the AFCT-57V6USZ over the operating conditions. Table 5 describes the performance of the receiver portion of the AFCT-57V6USZ over the operating conditions. The optical pulse characteristics of the transmitter are specified in the form of an eye pattern. When measured in accordance with [2], the mask shown in Figure 2 evaluates rise time, fall time, overshoot and undershoot.

• The supply current of the AFCT-57V6USZ is described in Table 6 below. The inrush current is defined as the additional inrush due to hot plugging.

• The characteristics for the control and status signals are shown in Table 7. Output status signals, TX_FAULT and RX_LOS, are all open-collector/drain, and the levels indicated assuming 4.7k-10k ohm pull-up resistor to Host_Vcc is present. The levels of MOD_DEF[1] and MOD_DEF[2] are also indicated assuming that they are pulled up with a 4.7k-10k ohm resistor to +3.3 V on host board. Table 8 indicates the voltage levels required to be delivered by the host to the transmitter differential serial data input TD+/-. Table 9 indicates the voltage level output from the receiver differential serial data output RD+/-.
