IWR1642: How to get the 4 RX ADC raw data

Part Number: IWR1642
Other Parts Discussed in Thread: IWR1843, AWR1642, AWR1843

Hi team:

We want to develop BSD function in IWR1642,but now we can only get its ADC raw data by LVDS interface, and the LVDS demo board is too big for us.

So do you have any suggestions?

Hi Carrier,

I've asked an expert to look into this and we should have an answer for you in the next few days.

Cheers,

Akash

Hi Carrier,

IWR1642 is single chip SOC, it has Arm micor controller and C6748 DSP embedded in the SOC.

LVDS is the debug interface for raw ADC capture. You could use FPGA to capture the LVDS signal as demonstrated in DCA1000.

Typically BSD function uses Automotive device qualified single chip device for example AWR1642/AWR1843 devices. If you need industrial grade device you could use IWR1642/IWR1843 devices.

You could refer to below TI design. http://www.ti.com/tool/TIDEP-0092

Design guide is given below.

Thanks for your reply.

You mean that I only can get the raw ADC data by LVDS interface, right ?
