OP5352 - 32 Digital Output - TTL
The OP5352 features 32 output channels operating at 5V (CMOS/TTL) or 3.3V (LVTTL).
Main Features
- The 32 output channels are grouped into two banks of 16 channels each.
- The signals of each bank are made available to the user at one DB37F connector of the chassis in which the module is installed.
- The voltage output for each bank is configurable for either 5V ±10% (CMOS/TTL Logic ) or 3.3V (LVTTL).
- Galvanically isolation to real environment signals provides protection to the simulator from damaging voltages.
Channel Description
Each channel implements the circuit shown below:
In addition, OPAL-RT provides a DB37 to DB37 prototype board (OP8320-4 - Transmission Line Termination Kit), which, when inserted in the cabling going from the simulator to the external device, allows tuning the impedance of the lines, so the signal quality is optimized. This helps to remove ringing, over or undershoots which can cause false triggering, stair-stepping, delays and loss of noise margin.
Voltage Jumper Settings
Each group of 16 channels can be configured for 5V or 3.3V operation, using the jumpers P3 and P4:
P3 | CH00-15 (VIN_ISO1) |
| |
P4 | CH16-31 (VIN_ISO2) |
|
Typical Use Cases
The OP5352 is ideal for interfacing with devices operating at low voltage.
TTL signals are not recommended for long-distance data transmission. We recommend using this board with cable lengths no longer than 1.5 meters (5 ft). When using longer lengths, OPAL-RT recommends terminating the lines to avoid over/undershoots or using alternative transmissions, such as differential mode (e.g: LVDS OP5355-3, RS422 OP5356-5 [5V] or OP5355-3 [3V3]).
For details on how to terminate the lines and to interconnect equipment with the OP5352 board, please refer to the WP CMOS/TTL opal RT_rev 1.0.
