TEF82XX ATB Issue

liuxy — Fri, 25 Jul 2025 08:59:56 GMT

Hello, I would like to test by bypassing the ADC and directly testing the RX to the analog port. We will use a spectrum analyzer to view the internal analog signals. May I ask where the relevant registers are located? Because I only saw the clock and power control related registers for the ADC and ATB. There is no reserved ATB port? Or is the RC receiving data default sent to the ADC and ATB port and no need for switching?

In register R2M0A_LO_INTERFACE_CONTROL_U16:0x000, I saw the enable settings for buffers B3, B2, and B1. However, I couldn't find the corresponding positions in the schematic. Could you please help me identify the locations? Or is it that the TEF82xx does not have these buffers?

Buffers B1 to B4 have been found in the data sheet. Thank you.

Hello,

I was talking with TEF82xx FAE and the ATB is internal and wont be discussed with customer.

I recommend you to get in touch with NXP FAE/Sales for further questions as such will require NDA at minimum,

Best regards,

Peter
