I want to use the AD9361 in CMOS Mode. I only use Rx1 and Tx1. Rx2 and Tx2 are disabled.
I have configured the register 0x12 = 0x04 to enable the CMOS Mode and the Single Port Mode (I want to use the P0 port only).
On a scope the CMOS data received and emitted by the AD9361 look like the timing described in the UG Manual.
However the AD9361 seems to not work properly when I send CMOS data on the Tx bus (P0[11:6]). For example if I send IQ data corresponding to a Single Tone on the Tx data port, the RF signal at the output of the Tx path is simply noise (with a strong level).
So my questions are :
- Which registers must be configured to enable the CMOS Mode ?
- What are the other configuration (software and hardware) that must be implemented to ensure a proper working in CMOS mode ?
