Hello,

From the documentation I can't quite understand what is the main differences between those two TDC1000 EVM.

The only thing I could find is:
-------------------------------------------------------------------------

The TDC1000-C2000 EVM (http://www.ti.com/tool/TDC1000-C2000EVM) has a VDD of 4.65V

while the TDC1000-TDC7200EVM (http://www.ti.com/tool/tdc1000-tdc7200evm) has a VDD of 3.7V
-------------------------------------------------------------------------

Could you please highlight some other main points?

Thanks.

Hello,

The largest difference between the two EVMs is the way that the time of flight is measured. In both cases the TDC1000 analog front end is used to generate START and STOP signals, and the time between those is measured to determine TOF. With the TDC1000-TDC7200EVM, the TDC7200 device measures the time, while on the TDC1000-C2000EVM, the C2000 measures the time.

Communication between the EVM and the GUI is done with the C2000 on the TDC1000-C2000EVM, while the TDC1000-TDC7200EVM has an MSP430 microcontroller for communication.

The TDC7200 provides higher accuracy of time measurement than is possible with the C2000, but otherwise the two EVMs have very similar capabilities.

Thanks Scott for your very prompt reply.
My only interest in those EVM is to drive Ultrasonic transmitter, the receivers will be connected to AFE1512EVM.
So, besides the difference in the VDD it should not matter for me which one to choose, is this right?
