Murata recommends a 4-layer PCB with a solid ground plane and a separate power plane for the oscillator circuit. The PCB layout should also minimize noise coupling and ensure good thermal dissipation.
To ensure reliable startup, Murata recommends applying a power-up sequence with a slow rise time (e.g., 10 ms) and ensuring that the power supply voltage is stable before enabling the oscillator. Additionally, a 10 kΩ to 100 kΩ pull-up resistor on the EN pin can help ensure reliable startup.
The NTPA7160LBMB0 is rated for operation from -40°C to +85°C, but the oscillator frequency may vary with temperature. For optimal performance, Murata recommends operating the device within a temperature range of 0°C to +70°C.
The output frequency of the NTPA7160LBMB0 can be adjusted by connecting a trimmer capacitor (e.g., 10 pF to 30 pF) between the XTAL1 and XTAL2 pins. The capacitor value and type may affect the oscillator frequency and stability.
Murata recommends using a 10 μF to 22 μF decoupling capacitor with a low ESR (e.g., X5R or X7R type) connected between the VDD and GND pins to ensure stable operation and minimize noise.
