AFE7222 - Out of use of ADC input pins

Other Parts Discussed in Thread: AFE7222

Hi All,

Would you mind if we ask AFE7222?

In case of out use ADC_B, as our recognition, ADC_B input pins that are not used can be left un-connected.
And we are not using channel B, power down this channel through SPI.

<Question>
The datasheet(on Address 0x167) says that "if any of the digital features(like interpolation, Fine mixer,
Coarse mixer, or GMC gain/phase or offset) are enabled, then the channelX can be independently powered down
using bits RX_CHA_PDN and RX_CHA_PDNSRC."

So, in order to power down independtly, should we set any digital features?
Only using bits RX_CHA_PDN and RX_CHA_PDNSRC, can we power down CHAX, or not?


Kind regards,

Hirotaka Matsumoto
