TSW1400 EVM and ADS62P49 EVM

Other Parts Discussed in Thread: ADS62P49, ADS62P48

Hi TI,

I am using TSW1400 EVM to interface ADS62P49 EVM via CMOS.

Connected CMOS Pin 1 on TSW1400 to pin 39 of ADS 62p49EVM board.

User LED 3 , 4 is not ON in the TSW 1400 board

I want to simply capture the noise.

1. Why will I get a Timeout error ?

thanks

    Hi Venky,

    The timeout error is caused by the FPGA not receiving a data clock from the ADC EVM.

    Have you looked at the users guide?

    http://www.ti.com/lit/ug/slau237a/slau237a.pdf

    It describes the connection of ADS62Pxx EVM, however it also seems to indicate that the default configuration of the ADC EVM is set for LVDS by default.  Have you made the changes to the ADC EVM to have it work on the parallel CMOS port?  Look at section 2.2.5.

    Have you tried using the LVDS connector on TSW1400?  I believe you can select the ADS62P48_49 in the ADC selection drop down.
