Part Number: AWR1243BOOST
Other Parts Discussed in Thread: AWR1243

hello

I am studying AWR1243, I found CSI2 ports which include Differential debug port,,

Differential debug port 1: HS_DEBUG1_P M15 HS_DEBUG1_M M14
Differential debug port 2: HS_DEBUG2_P N15 HS_DEBUG2_M N14

what is it used for? how can i use it?

any document I can read?

thank you very much!!!

Best regards!!

Hello ,
The HS_DEBUG lines are not part of the CSI interface, they are part of the different high speed interface (LVDS) used only for debug purpose.
If you are using CSI interface you dont need to use those lines.

Hello,
The HS_debug lines allow a LVDS interface , which is an alternative option to the CSI interface. This has more lines than the CSI interface , and hence additional lines.

Hi, Vivek

As you said, the HS_debug lines belong to LVDS interface. Can you tell me that what do these two HS_debug lines represent respectively? LVDS_VALID and LVDS_FRCLK?

Jason

Hello Jason,
The LVDS_FRCLK is a basically an ADC sample clock . The is one clock cycle for one ADC sample width. If you have 16bit ADC samples this signal will be like a clock for 16bits.
LVDS_VALID would be high during the complete period of chirp data transfer out.
