CWX813-018.432M datasheet by Connor-Winfield

CWX813-018.432M Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the CWX813-018.432M?
  Connor-Winfield recommends a 4-layer PCB with a solid ground plane, and to keep the crystal and capacitors as close to the oscillator pins as possible to minimize noise and parasitic inductance.
• How do I ensure the CWX813-018.432M oscillator starts up reliably in my design?
  To ensure reliable startup, Connor-Winfield recommends using a 1-2 kΩ pull-up resistor on the oscillator enable pin, and a 10-100 nF decoupling capacitor on the power supply pin, close to the oscillator.
• What is the maximum operating temperature range for the CWX813-018.432M?
  The CWX813-018.432M is rated for operation from -40°C to +85°C, but Connor-Winfield recommends derating the frequency tolerance by 5 ppm/°C for temperatures above 70°C.
• Can I use the CWX813-018.432M in a design that requires a different frequency than 18.432 MHz?
  No, the CWX813-018.432M is a fixed-frequency oscillator and cannot be adjusted to operate at a different frequency. Connor-Winfield offers other products with different frequencies, or custom frequencies can be ordered with a minimum order quantity.
• What is the typical power consumption of the CWX813-018.432M?
  The CWX813-018.432M typically consumes around 20-30 mA, but this can vary depending on the specific application and operating conditions. Connor-Winfield recommends consulting the datasheet and application notes for more information.
