Design Notes
For optimal RF performance, place the STA8089GADTR on a dedicated ground plane with a 50-ohm impedance-controlled RF trace from the antenna to the RF_IN pin. Keep the trace as short as possible and add a matching network as recommended in the datasheet. Use a low-ESR 10uF capacitor on VCC and a 100nF capacitor on VCC_RF, placed close to the pins.
The STA8089GADTR operates from 1.8V to 3.3V. Use a low-noise LDO to supply the VCC and VCC_RF pins to avoid power supply noise that could degrade GPS sensitivity. The VCC_IO pin should be connected to the same voltage as the interfacing logic (e.g., 3.3V for UART). Ensure adequate decoupling with 10uF and 100nF capacitors on each supply pin.
Do not route high-speed digital signals (UART, SPI, USB) near the RF input trace, as this can introduce noise and reduce sensitivity. Use a 26 MHz crystal with a load capacitance matching the datasheet specification (typically 10pF). The 32.768 kHz RTC crystal is required for timekeeping and should be placed close to the IC. Ensure the antenna has a clear view of the sky for optimal performance.
