Pin Configurable/Selectable Oscillators

The DSC400-4444Q0022KE1T is an example of pin configurable/selectable oscillators, which are clock sources used in many electronic circuits. It features a low power 32.768kHz oscillator, which can be programmed using three pins.

The oscillator is used to generate clocks of various frequencies and is mainly found in embedded systems, communications applications and other portable low power electronics. The clock source has the ability to be programmed by driving the three pins (select-pin S, divider BYP and program-pin A) either in logic high or logic low state. By combination of these pin states, the oscillator can generate up to 24 different clock frequencies within its operational range.

The working principle behind the DSC400-4444Q0022KE1T oscillator lies in the fact that 32.768 kHz is generated through a quartz crystal. This quartz crystal is connected in parallel with a load capacitor. The Load capacitor is programmed by virtue of the combination of the pin states by virtue of the pull-up and pull-down resistors typically connected to the pins. This forces the quartz-crystal to produce an frequency as per the pin state.

The oscillator has a frequency range from 32.768 to 7.68 MHz and contains integrated digital logic to divide this clock frequency according to body profile and the logic state of the divider pin. The dynamic frequency range, the high stability of the clock source and low power consumption makes it desirable in various applications.

The great feature of the clock source is that it has a wide application field. In high frequency or ultra-low frequency electronic products, the clock source is widely used. It can also be used in PCs, mobile phones, electronic watches, modems, printers or similar electronic products. It helps them to accurately measure time and improve the accuracy of various electronic equipment.

In summary, the DSC400-4444Q0022KE1T oscillator is a versatile and highly reliable clock source. It’s versatile enough to be used in many types of applications, providing a wide range of frequency options, low power consumption and a high level of accuracy. With these features, it makes for a great choice for a reliable clock source in any product.
