Quad 4 Fold AND/OR/MAJ, NIM-TTL TTL-NIM Translator, Fan-In Fan-Out
- Four independent sections with four channels each
- TTL and NIM inputs automatically detected
- NIM/TTL selectable output level
- AND, OR, Majority function with selectable number of inputs
- Logic Fan In / Fan Out
- Selectable direct or negated output
The CAEN Mod.V976 is a 1-unit VME module housing four 4-input Coincidence, Fan in/Fan out and NIM – TTL Adapter sections. The module has 16 inputs and 16 outputs on LEMO 00 connectors. Each section can either operate as a 4 channel NIM-to-TTL or TTL-to-NIM translator or perform the AND/OR logic functions. It is possible to use two or four sections together to obtain an 8 or 16 input majority. The module works also as Fan out and supports the Majority logic function. The board recognises automatically NIM and TTL signals (no input-type selection is necessary).
In more detail, the supported functions are the following:
- 16 ch TTL – NIM, NIM – TTL Translator
- 8 ch TTL – NIM + 8 ch NIM – TTL Translator
- 4 X ( 2, 3, 4 in / 4 out AND/OR)
- 2 X (8 in / 8 out Majority)
- 16 in / 16 out Majority
- 2 X (1 to 8) Fan out
- 1 to 16 Fan out
The desired function can be selected via front-panel and internal switches.
Some extra functions can be obtained by cascading properly the module’s sections.
The output signals are equal in duration to the time during which the performed logical operation has a TRUE status. The output width cannot thus be programmed.
Input signals can be indifferently either NIM or TTL levels; the outputs can be programmed to provide either NIM or TTL levels as well (either normal or negated, selectable via front panel switches).
The presence of incoming input signals is signalled by 16 green LEDs (one per channel).
The Majority LEDs light up when the Majority is being performed.
