Pin Description
A brief description of all of the electrical connector pins follows. The connector has staged contacts, so that hot-plug-
ging can be performed. See Table 10.
Table 10. Pinout
Hot-Plugging Sequence
The ground, VCC and other pins designated as the se-
quence (1) pins engage first during hot-plugging. The
sequence (2) pins connect second during hot-plugging
followed by the sequence (3) pins. Conversely, when
the module is unplugged from the host system, the se-
quence (3) pins disengages before the sequence (2) pins
disengages and then followed by the sequence (1) pins.
Inserting or removing the AFCT-57V6NSZ will disrupt
data transmission. This disruption occurs when the
downstream receiver (e.g. deserializer phase-lock-loop)
resynchronizes to a different bitstream signal. When this
occurs, the downstream system will recognize the asso-
ciated error (e.g. comma detect, loss-of-light, disparity,
CRC, and frame errors).
It is the responsibility of the system integrator to assure
that no thermal, energy, or voltage hazard exists during
the hot-plug-unplug sequence. It is also the responsibility
of the system integrator and end-user to minimize static
electricity and the probability of ESD events by careful
design.
