ECS-110.5-20-4 Application Field and Working Principle

Crystal unit ECS-110.5-20-4 is a highly precise and stable crystal with much wider operating temperature range compared to others of its kind. It is widely used in industrial automation and other related fields. This paper will introduce its application field, specific parameters and basic working principle.

1. Application Field

The ECS-110.5-20-4 crystal unit is widely used in Control panels, oscillators, frequency modulation (FM) and frequency divider applications. It is capable of operating over a wide range of frequencies, and its highly stable frequency output can be used to provide precision timing and frequency reference in many industrial applications. It is commonly used in high precision time-keeping systems, and many other devices.

Moreover, it is temperature-compensated for operation over wide ambient temperature ranges, and its frequency stability is within 0.07% when operated within -10 to 70 degree centigrade. Not only that, its overall accuracy after temperature compensation is greater than ± 1.0 ppm.

• Equivalent series resistance (ESR): 20Ω
• Load capacitance: 4.8pF~20.0pF
• Voltage: 3.3V/5.0V
• Storage temperature range: -55~125°C
• Frequency tolerance over temperature range: 0.07%
• Overall accuracy after temperature compensation: ±1.0 ppm

3. Working Principle

The ECS-110.5-20-4 crystal unit is a type of crystal oscillator that uses a quartz crystal as its resonator. When a voltage is applied across the crystal, it starts oscillating at its resonant frequency, producing an alternating electric field. This alternating electric field will cause the crystal to vibrate and produce corresponding frequency outputs. The frequency of the outputs depends on the size and shape of the quartz crystal. The ECS-110.5-20-4 has a frequency range of 10.5MHz and a load capacitance range of 4.8pF – 20.0pF, and its frequency stability is within 0.07% when used within temperatures ranging from -10°C to 70°C.

The frequency output from the quartz crystal is then amplified and filtered before being output from the ECS-110.5-20-4 crystal unit. This ensures that any unwanted noise signals are filtered out and that the output waveform has minimal distortion.

4. Conclusion

The ECS-110.5-20-4 crystal unit is a highly precise and stable crystal, capable of operating across a wide temperature range with superior accuracy. Its application field is mostly in the industrial automation and related fields, used in frequency modulation and frequency dividers, as well as in many high precision time-keeping systems. Understanding its specific parameters and working principle can help us better utilize and maximize its performance.
