3 Connector Definitions

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: Analogue Output.

I: Input, TTL compatible if nothing else stated.

IO: Input / Output. TTL compatible if nothing else stated.

IOT: Bi-directional tristate IO pin.

IS: Schmitt-trigger input, TTL compatible.

IOC: Input / open-collector Output, TTL compatible.

IOD: Input / Output, CMOS level Schmitt-triggered. (Open drain output)

NC: Pin not connected.

O: Output, TTL compatible.

OC: Output, open-collector or open-drain, TTL compatible.

OT: Output with tri-state capability, TTL compatible.

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.
