Regarding the DFE-Q V2.1 power down mode means that
• the DSP clock is turned off
• all digital circuits (excluding the IOM
• no timing signals are delivered (CLS0, ... , CLS3)
• as the internal control logic of the activation/deactivation procedures are event driven
Regarding a connected AFE power down mode means that
• no signal is sent on the U-interface
• only functions that are necessary to detect the wake up conditions are kept active
• transmit path, receive path and auxiliary functions of the analog line port are switched
• the ADC, the relevant output is tied to GND.
• the DAC and the output buffer; the outputs AOUTx/ BOUTx are tied to GND.
• the internal DC voltage reference is switched off.
• the range and the loop functions are deactivated.
Data Sheet
power is saved as soon as one of the four lines transits in the DEACTIVATED state
to a low power consuming mode when the power down function is activated. This
implies the following:
