Electrical Description
The supply current of the AFCT-57V6USZ is described in
Table 6 below. The inrush current is defined as the ad-
ditional 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 indi-
cated 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+/-.
