CXD1968AR
Energy Saving Modes
Low-power Standby Mode
This mode reduces the nominal power consumption of the CXD1968AR in IF mode from 140mW to 10mW.
To obtain maximum benefit it is necessary in software to;
Disable PLL and stop internal clocks
Power-down the ADC
Recovery from low-power standby mode can be achieved by cold reset to all blocks.
Example: 0xD8 0xA9 0x41 ; power-down PLL and stop clock
0xD8 0xB9 0x01 ; power-down ADC
Ultra Low-power Shutdown Mode
This mode reduces the nominal power consumption of the CXD1968AR in IF mode from 140mW to < 1mW.
This mode is entered through external control of OSCEN (Pin 40). Grounding this pin will stop the crystal
oscillator and all on-chip activity.
The CXD1968AR should be reset when resuming from shutdown mode.
