Hello,

I'm working with AWR2944 Evaluation Board PROC113D .There are VIOIN connected to 3.3V and VIOIN_18 connected to 1.8V .It's not clear to me which signals in the AWR2944 are using the 3,3V on the VIOIN and which signals are using 1.8V on VIOIN_18 .Can any one help in this?.

I have VIOIN connected to 3.3V and VIOIN_18 connected to 1.8V.I don't know whether the signals on AWR2944 named MCU_CLKOUT , PMIC_CLKOUT ,MSS_GPIO_0 to MSS_GPIO_11, MSS_GPIO_17, MSS_GPIO_28, MSS_GPIO_30 and MSS_GPIO_31 have a logic determined by VIOIN or by VIOIN_18.Please help me in this as it's not clear in datasheet.

3.3V is used for Ethernet. I'll need to confirm the others on VIOIN_18. Allow me to get back to you on that.

Hello,

It is VIOIN. VIOIN is applicable for all GPIOs (expect CSI & LVDS).

VIOIN_18 is dedicated for ADPLL, CSI, LVDS.

Thanks,
