TX SDK V1/V2

What is the difference between TX SDK V1/V2? Is the only difference that one uses the LM96551 and the other one the LM96550? The price difference of these boards is 200$.

The LM96551 offers "floating supply voltages for output stages". What does it mean?

    Hello,
    Here is the difference between TX-SDK-V1 and TX-SDK-V2:
    The difference between the TX-SDK-V1 and TX-SDK-V2 is the pulser. V1 is for the LM96551, which has the floating supplies VPF and VNF built-in (generated internally). V2 is for the LM96550, which the customer has to apply the VPF and VNF supplies externally. Technically, the TX-SDK-V2 can be used for the LM96551 too as long as one doesn't apply any voltages to VPF and VNF pins.
    For the LM96551, the floating supplies are generated internally.

    The price for the TX-SDK-V1 is $999, and the TX-SDK-V2 is $799 on the web. If you can provide the external supplies to VPF and VNF, you can save the $200 difference.

    Hello,

    Thank you very much for your reply. Now we bought the TX_SDK_V2. For the first tests we don’t need +/- 50V. Is it possible to configure J_SUB in the “1-2” position and to choose

    -          -10 V for VSUB

    -          +/-10V for VPP and VNN

    -          +/-5V for VPF and VNF

    -          +/-10V for VPN and VDN

    -          +/-5V for VDD and VSS

    -          +3.3V for the Digital IO Supply

    -          +1.8V for VDDA and VDDC

    ?

    Kind Regards

    Hi Biggik,

    I think you meant the following instead (shown in color):

    -          +/-10V for VPN VDD and VDN

    Yes, I think what you are proposing will work.

    Hi Hooman,
    thank you very much for your reply!
    I took the VPN and VDN from the TX_SDK_V2 Users Guide chapter 2.3. But you are right it should be VDD and VDN. Maybe someone wants to correct it.

    Regards
