AFE4400 power specification

Other Parts Discussed in Thread: AFE4400

I have some questions about power consumption of AFE4400

1. From AFE4400 datasheet page 11(shown below), what does the "Power-down Rx alone" mean in detail? Does it mean disable all the circuit in RX excluding the 3V to 1.8V regulator which is shown below the table ?

2. May i know the power consumption of "Rx Analog modules" and "Rx Digital" shown in the figure above in the typical condition?

3. What is the Quiescent Current of Rx_ANA_SUP to 1.8V Regulator shown above ?

Best Regards,

Tim

Hello Tim,

In the powerdown RX mode, most of the digital and analog modules are powered down except for the regulators, , internal oscillator, internal bandgap and reference voltage circuitry.

Could you explain the need for understanding the internal block level current consumption?
Do you notice any additional current draw from the AFE compared to what is specified in the datasheet for your test conditions?
