9001 HDL Common 2r2t question/confusion

Question

We have custom board with 9002 and the intent is to use IQ channels on Tx1 Rx1 Tx2 Rx2. 
 we don't want any dependency between the 1st and 2nd Rx/Tx. (besides using a sample rate that is related but not equal) 
 We dont want to share or use the RX12 with 4 channels. 
 We also dont want to share the RX clock to use it for Tx. 
 
 So for these settings: Common 2r2t Support should be 0? 
 
 And for independent 1r1t Support should this be 1? 
 
 Thank you

Hi, 
 take a look into the AXI ADRV9001/9002 IP Core doc at https://wiki.analog.com/resources/eval/user-guides/adrv9002/axi_adrv9002 , there are the descriptions for each parameter. 
 Independent 1R1T can be enabled by setting INDEPENDENT_1R1T_SUPPORT parameter to 1, and USE_RX_CLK_FOR_TX as 0 sets the TX to not use the RX clock. 
 
 Common 2r2t as 0 will put the core in Mode R1, disabling the DAC Channels 2 and 3 (first channel is Channel 0). 
 
 Also, you can test in simulation the configs with the tb at github.com/.../adrv9001)
