The lowest operation power state of PT8R1002 is Sleep state, where all clocks including RF and baseband and circuits in the
PT8R1002 is placed in their minimum power mode. In this mode, the control register can be accessed through serial interface
logic and retain their programmed value. To enter into
Sleep state
, power-down command which sets power-down of clock
generator including crystal buffer should be programmed through the serial interface. After power-down command, the DATACLK
from the PT8R1002 will stop until it comes back to
Idle state
. To escape from
Sleep state
, power-up command which sets power-
up of clock generator should be programmed through the serial interface. After power-up command, the DATACLK will start
again from the PT8R1002 into external baseband.
