Application Field

The ECS-PEC33-1000-BN oscillator is widely used in telecom, consumer electronics, automotive, and medical applications. As a low-jitter oscillator, it finds particular use in high-speed digital signal processing applications, such as low-latency video transmission in automotive applications. Its high performance is also suited to encryption and authentication protocols requiring a secure encryption key, real-time communications, advanced servo and robotics applications, and high-speed frequency synthesizers. This oscillator has currently been employed in various products, from sophisticated industrial machinery to consumer electronics.

Working Principle

The operation of the ECS-PEC33-1000-BN oscillator is based on the Pierce oscillator topology, which combines the advantages of the Colpitts oscillator and the crystal oscillator. The Pierce oscillator employs an NPN transistor as the heart of the oscillator circuit. A Colpitts oscillator is used to provide an oscillating bias to the transistor, while a quartz crystal provides a well damped frequency reference for the oscillator. The bias voltage is applied across the transistor base-emitter junction, causing it to alternately turn on and off. The output of the transistor is then fed back to the Colpitts oscillator, causing the bias voltage to switch states. This process creates an oscillating signal, of which the frequency is determined by the frequency of the quartz crystal.

ECS-PEC33-1000-BN oscillators offer excellent temperature stability and long-term stability, due to their use of an external temperature compensating resistor and high-precision, tightly-tolerance crystals. The oscillator also provides an output frequency tolerance of ±0.1ppm, jitter of less than 0.1ps, and power consumption of 1W max. This low-power oscillator is also available with an optional integrated frame, making the device suitable for applications with space constraints.

Overall, the ECS-PEC33-1000-BN is an effective and low-cost oscillator ideal for a wide range of applications, including industrial machinery, consumer electronics and advanced servo and robotics applications. Its Pierce oscillator design provides excellent temperature stability and long-term stability, as well as low power consumption.
