Interface Description
4.1
Signal naming
Signal names are usually written in capital letters. They are noted in positive logic (positive asserted). If the
signal is negative asserted an “n” will be added as prefix to the signal name.
Type:
The type describes the electrical characteristics of the signal. The following types are available:
•
I
Input
•
O
Output
•
DN
Negative Differential I/O
•
DP
Positive Differential I/O
•
P
Power supply
•
3.3V TTL
TTL compatible signal with 3.3V high level and 0V low level.
•
50V tolerant Accepts input voltage levels up to 50V (2.5V high voltage threshold)
