    TRSF3232ECDR Frequently Asked Questions (FAQs)

    • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. Additionally, it's recommended to use a ferrite bead or a pi-filter to filter out high-frequency noise.
    • The TRSF3232ECDR requires a power-on reset (POR) signal to ensure proper initialization. A 10uF capacitor between VCC and GND, and a 1kΩ resistor between VCC and POR are recommended. Also, ensure that the input voltage is within the recommended range of 2.7V to 5.5V.
    • The TRSF3232ECDR can support clock frequencies up to 32 kHz, but it's recommended to use a clock frequency of 32.768 kHz for optimal performance.
    • To configure the TRSF3232ECDR for low-power mode, set the PD bit in the control register to 1. This will put the device in power-down mode, reducing the current consumption to less than 1 μA.
    • Texas Instruments recommends a crystal oscillator circuit with a 12pF load capacitance and a 10MΩ feedback resistor. The crystal frequency should be 32.768 kHz, and the crystal should be connected between the XIN and XOUT pins.
