Customer asked me few questions about the power: (TX-SDK-V1 - bought the EVM)
1. Can I connect the two -50V together (VSUB and VNN) ?
In the user manual it says something blurred: what does it mean “However”? what will happen? :
“ Note that VSUB and VNN (negative HV supply of the LM96551) may be tied together and powered by the same -50V to minimize the number of bench power supplies.
To do this, jumper J_SUB (see Figure 4) must be configured in the “1-2” position.
However, it is recommended to configure jumper J_SUB in the default “2-3” position such that VSUB and VNN are separated.”
2. If I do connect them together, should I turn both VSUB and VNN first in the “ON” sequence and last in the “OFF” sequence.
3. For all power signals, what will be the ‘0’/ ‘1’ logic level ?
4. when I turn the power supply “Off” , there may be up to 0.6V.
5. Please approve that a power supply with a Ripple and Noise <1% or 50mV pk-pk, and Voltage Accuracy <1% of set voltage will be good for the EVB TX_SDK_V1
Any recommendation or block diagram for connecting the “power supply” to the “sequencer” with the PC and to the “EVB TX_SDK_V1” ?
The sequence to turn the system on should be:
By the way - it is not possible to enter TX-SDK-V1 as a part number!
