Smart Machine Smart Decision 3 Application Interface Specification 3.1 Power Supply The power supply pins of SIM5320A include VBAT_RF and VBAT_BB. VBAT_RF directly supplies the power to RF PA; VBAT_BB supplies the power to the baseband system. For the VBAT_RF, the ripple due to GSM/GPRS emission burst (every 4.615ms）may cause voltage drop, and the current consumption rises typically to peak of 2A. So the power supply must be able to provide sufficient current up to 2A.
PAGE 22
Smart Machine Smart Decision 3.1.2 Design Guide Mostly, user connects the VBAT_RF and VBAT_BB pins with one power supply. Make sure that the input voltage at the VBAT_BB pin will never drop below 3.3V even during a transmit burst when the current consumption rises up to 2A. If the power voltage drops below 3.3V, the module may be shut down automatically. Using a large tantalum capacitor (above 100uF) will be the best way to reduce the voltage drops.

Smart Machine Smart Decision Temperature monitor ADC interface can be used to monitor the temperature of power components to avoid over temperature. An external NTC resistor (such as NCP15XH103F03RC) can be used to measure the device temperature. The ADC1 pin can be used as external voltage detection. Please refer to Chapter 3.17. ADC2 is the ADC input pin for temperature detection. The following figure shows the application circuit.

Smart Machine Smart Decision 3.11 PCM Interface SIM5320A provides hardware PCM interface for external codec. The PCM interface enables communication with an external codec to support hands-free applications. SIM5320A PCM interface can be used in two modes: the default mode is auxiliary PCM (8 KHz long sync mode at 128 KHz PCM CLK); the other mode is primary PCM (8 KHz short sync mode at 2048 KHz PCM CLK). In short-sync (primary PCM) mode, SIM5320A can be a master or a slave.

In Master Mode, the Module drives the clock and sync signals that are sent to the external codec. When it is in Slave Mode, the external codec drives the clock and sync signals which are sent to the module. Both PCM modes are discussed in this section followed by additional PCM topics.
