TSW1400EVM: DDR to SDR and sample wise mode

Part Number: TSW1400EVM

Hi,

Customer are using TSW1400EVM to test an adc. But they could not find where to change the DDR to SDR mode. According to them, they actually find configuration files on 1400 details-> adc files. But it seems there are not enough explanations

For their inquiry, see details below.


1. I want to know how to switch DDR and SDR mode for TSW1400EVM?
2  Could you explain the difference between bitwise and sample wise? And how I switch these modes? I have a problem about sample-wise mode of TSW1400. I am wondering how to configure the board to this mode.
3. Another problem, if I want to measure an adc with 1 GHZ LVDS output, how should I set the TSW1400EVM  configurations to test it.

Thank you in advance.

Regards,
Maynard
