  • Page 21: Application Interface Specification

    Smart Machine Smart Decision Application Interface Specification Power Supply The power supply range of SIM5320JE-TE is from 3.3V to 4.2V. For the VBAT, 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.
  • Page 22 Smart Machine Smart Decision tantalum capacitor (above 100uF) will be the best way to reduce the voltage drops. If the power current cannot support up to 2A, users must introduce larger capacitor (typical 1000uF) to storage electric power, especially GPRS multiple time slots emission. For the consideration of RF performance and system stability, another large capacitor (above 100uF) should be located at the VBAT pin and some multi-layer ceramic chip (MLCC) capacitors (0.1uF) need to be used for EMC because of their low ESR in high frequencies.
