Pin Description
Please note that all module connections are not to exceed their
expressed maximum voltage or current. Maximum signal input values
are indicated in the corresponding controller manuals/data sheets. As
damage from improper connections varies according to use and
application, it is the user's responsibility to take appropriate safety
measures to ensure that the module connections are protected from
overloading through connected peripherals.
As
Figure 4
indicates, all X-Arc bus signals extend to one surface
mount technology (SMT) connector (0.635 mm) lining on side of the
module (referred to as phyCARD-Connector). This allows the
phyCARD-M to be plugged into any target application like a "big
chip".
The numbering scheme for the phyCARD-Connector is based on a
two dimensional matrix in which column positions are identified by a
letter and row position by a number. Pin 1A, for example, is always
located in the upper left hand corner of the matrix. The pin numbering
values increase moving down on the board. Lettering of the pin
connector rows progresses alphabetically from left to right (refer to
Figure 4
).
The numbered matrix can be aligned with the phyCARD-M (viewed
from above; phyCARD-Connector pointing down) or with the socket
of the corresponding phyCARD Carrier Board/user target circuitry.
The upper left-hand corner of the numbered matrix (pin 1A) is thus
covered with the corner of the phyCARD-M marked with a triangle.
The numbering scheme is always in relation to the PCB as viewed
from above, even if all connector contacts extend to the bottom of the
module.
The numbering scheme is thus consistent for both the module’s
phyCARD-Connector as well as the mating connector on the
