Oscillators are widely used in a variety of industries and applications. In particular, the ASCSM-2.048MHZ-LR-T oscillator has become an increasingly popular solution for a variety of industries. In this article, we will discuss the application field and working principle of the ASCSM-2.048MHZ-LR-T oscillator.

The ASCSM-2.048MHZ-LR-T oscillator is a low-power solution that has become increasingly popular due to its low cost and power consumption. It is most often used in consumer electronics, automotive, and communications industries, as well as for embedded systems. This oscillator is also commonly used in these industries because it is capable of generating a highly precise timing signal, with a maximum frequency of 2.048 MHz and a clock jitter of only 1.2 ns.

The ASCSM-2.048MHZ-LR-T oscillator utilizes a Pierce oscillator topology which consists of a single inversion-gain amplifier, such as a differential pair, connected to the crystal oscillator shown in Figure 1. The amplifier is connected directly to the load capacitor, and at the same time is decoupled from the crystal oscillator by means of a capacitor. This combination of amplifier and capacitor acts as a high-pass filter, allowing the passage of the desired clock signal and rejecting any noises caused by the environment.

In the beginning, the amplifier has a linear behaviour and its gain is precisely established with values of the resistors. A feedback circuit is formed by the amplifier and the resistors, reducing the gain gradually until the output reaches a stable oscillation frequency. Due to the resonance effect of the capacitor and load, the amplitude of the oscillation increases and reaches a steady value.

Figure 2 shows the response of the oscillator to a small change in the load resistance. As the oscillator frequency reaches a slightly lower frequency which can be observed at the extreme lower part of the graph, the amplitude tends to decrease considerably. Thus, it is necessary to add a small amount of resistance to the load for it to operate properly.

The difference between the ASCSM-2.048MHZ-LR-T oscillator and traditional quartz crystal oscillators is that the latter requires a connection between the crystal, while the former does not. As a result, the ASCSM-2.048MHZ-LR-T oscillator helps reduce costs and installation time, making it suitable for a variety of applications.

In conclusion, the ASCSM-2.048MHZ-LR-T oscillator is a highly precise frequency source that is capable of generating highly precise timing signals with low power consumption. It is a cost-effective solution that has become increasingly popular in the consumer electronics, automotive, and communications industries, as well as for embedded systems. The unique Pierce oscillator topology of this oscillator, which requires no connection to a crystal, helps reduce the costs of installation and maintenance.
