AFE7422EVM: Can this part support two channels in HBM as long as the data fits in the 8 lanes at 15Gbps per lane or less?

Part Number: AFE7422EVM
Other Parts Discussed in Thread: AFE7422

Hi team,

My customer is evaluating this part via the EVM and is confused by some differences in performances in the EVM and the part. 

In the EVM (in contrast to the datasheet) it appears that in high bandwidth mode (HBW) the device is limited to just one ADC channel (RX MODE 1 in the EVM) even though the spec talks to only DDC0 in HBW while there are two DDC0’s in the package. So can this part support two channels in HBM as long as the data fits in the 8 lanes at 15Gbps per lane or less?
