07/ Connector Definition - Kontron mITX-BDW-U Manual

07/ CONNECTOR DEFINITION
The following sections provide pin definitions and detailed description of all on-board connectors.
The connector definitions follow the following notation:
COLUMN NAME DESCRIPTION
Pin Shows the pin-numbers in the connector. The graphical layout of the connector
definition tables is made similar to the physical connectors.
Signal The mnemonic name of the signal at the current pin. The notation "XX#" states that
the signal "XX" is active low.
Type AI: Analogue Input.
AO:
I: Input, TTL compatible if nothing else stated.
IO: Input / Output. TTL compatible if nothing else stated.
IOT:
IS: Schmitt-trigger input, TTL compatible.
IOC:
IOD: Input / Output, CMOS level Schmitt-triggered. (Open drain output)
NC:
O: Output, TTL compatible.
OC:
OT:
LVDS: Low Voltage Differential Signal.
PWR: Power supply or ground reference pins.
Ioh: Typical current in mA flowing out of an output pin through a grounded load,
while the output voltage is > 2.4 V DC (if nothing else stated).
Iol: Typical current in mA flowing into an output pin from a VCC connected load,
while the output voltage is < 0.4 V DC (if nothing else stated).
Pull U/D On-board pull-up or pull-down resistors on input pins or open-collector output
pins.
Note Special remarks concerning the signal.
The abbreviation TBD is used for specifications which are not available yet or which are not
sufficiently specified by the component vendors.
