AIS Baseband IC with/without RF Synthesiser
CMX7032/CMX7042
7.11 Powersave
The CMX7032/CMX7042 implements a comprehensive powersaving scheme which will automatically
enable the sections of the device that are required and return them to their powersaved state when no
longer needed. In addition, a user defined Sleep mode maybe enabled which allows the device to drop into
power-saving mode should a Receiver channel not detect any activity at the start of the AIS burst. This
feature should be used with care to ensure that any peripheral circuits are powered-up again in time to
receive the following burst correctly.
When an Rx channel enters or leaves Sleep mode, an Rx State IRQ may be asserted, which allows the
host to powersave other external circuits under its control.
A “Deep Sleep” mode is also available through the Configuration mode which halts all signal processing
activity and allows the analogue functions to be disabled so reducing power consumption to the lowest
level – see section 7.4.14
