A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common ground point for the analog and digital grounds.
Use a high-quality decoupling capacitor (e.g., 100nF) close to the VCC pin, and ensure the power supply is stable and noise-free. Add a 10uF capacitor in parallel to the decoupling capacitor for additional filtering.
The recommended clock frequency is 16 MHz, but the device can operate up to 20 MHz. Ensure the clock signal is stable and has minimal jitter.
Set the PD0 and PD1 pins to '1' to enable low-power mode. In this mode, the device consumes minimal power, but some features may be disabled. Refer to the datasheet for specific details on low-power mode operation.
The L99H01QFTR can operate from -40°C to 125°C (junction temperature). Ensure proper thermal management and heat dissipation to prevent overheating.
