CTS Corporation recommends a symmetrical PCB layout with a solid ground plane, and keeping the oscillator away from high-frequency noise sources. A minimum of 2-layer PCB is recommended, with the oscillator on the top layer and the ground plane on the bottom layer.
To ensure reliable startup, CTS recommends a power-up ramp time of at least 1ms, and a power supply voltage that reaches the minimum specified voltage (1.65V) within 100ms. Additionally, the oscillator should be decoupled with a 10nF capacitor between VCC and GND.
While the datasheet specifies an operating temperature range of -40°C to 85°C, CTS Corporation recommends derating the oscillator's frequency stability and aging characteristics for operation above 70°C. Consult with CTS Corporation for specific guidance on high-temperature operation.
Yes, the 406C35B44M54500 is designed to meet EMI requirements. CTS Corporation recommends following proper PCB layout and shielding techniques, such as using a metal shield or a shielded enclosure, to minimize EMI emissions.
The oscillator's output signal is a CMOS-level signal, which can be directly connected to a microcontroller or other digital circuitry. However, CTS Corporation recommends using a series resistor (e.g., 1kΩ) to limit the output current and prevent damage to the oscillator or downstream components.
