# DIOT RTM Slow Analog 8i 4o
|
|
|
|
|
|
## Specifications
|
|
|
|
|
|
This card is intended to be used on DIOT as rear module (RTM) and must be compatible with V2 DIOT backplane BUT [V1 PB FMC](https://ohwr.org/project/diot-pfc-ku/wikis/home).

## Inputs
|
|
|
- Eight independent inputs single-ended
|
|
|
- 1 MSMPS, selectable input bandwidth per channel 25 kHz and 220 kHz.
|
|
|
- Range of +/-10V required (may be switchable to +/-5V)
|
|
|
- Preferably LEMO 00 connectors (may be double ones)
|
|
|
- Inputs protection to +/-10.7V.
|
|
|
- Additional inputs filter to 240kHz (-3dB).
|
|
|
|
|
|
## Outputs
|
|
|
- Four independent outputs single-ended
|
|
|
- Output range must be +/-10V (or only 0-10V ?)
|
|
|
- Slow sample rate as it is used only for HVPS reference (100 kSPS)
|
|
|
|
|
|
## Proposed architecture and components
|
|
|
- ADC AD7606C-16
|
|
|
- gateware compatible with RAT AD7609 [Remote Acquisition Tranceiver (RAT)#1.AD7609driver](https://wikis.cern.ch/pages/viewpage.action?pageId=226231836#RemoteAcquisitionTranceiver(RAT)-1.AD7609driver) ?
|
|
|
- DAC AD5764
|
|
|
To be added:
|
|
|
- level shifters to add VIO compatibility (ref. https://ohwr.org/project/diot-pfc-ku/issues/72)
