Oscillators: TD-24.576MDD-T Application Field and Working Principle

The TD-24.576MDD-T oscillator is a widely used device in a variety of industries. It is designed to convert electrical signals into pulses, thereby driving the operation of many machines and systems. This oscillator is known for its output timing, stability, and temperature range. This article investigates the TD-24.576MDD-T oscillator’s application field and working principle.

Application Field

The TD-24.576MDD-T oscillator is typically applied in Digitally Controlled Oscillators (DCOs). DCOs are used in electronically-controlled pulse-width modulation systems. Examples are spread-spectrum clock generators, phase-locked loops, and delay-locked loops. Therefore, TD-24.576MDD-T oscillators can be used in a variety of industries, ranging from consumer electronics to industrial automation.

Apart from this, the oscillator is also used in clocks and communication systems, including USBs, Ethernet, SCPIs, RFIDs, PLLs, and DDR2s. Certain PLL systems use a slightly modified form of the oscillator, which is known as the TD-24.576MDD-SWP. This type of oscillator is mainly used in Asynchronous Transfer Mode (ATM) and synchronous digital hierarchy (SDH) applications.

Working Principle

The TD-24.576MDD-T oscillator is essentially a memory device which works by storing patterns of electrical signals. The oscillator operates by alternately releasing and storing pulses of electrical signals. The release period is known as ‘relaxation time’, and the storage period is known as ‘refractory period’.

The frequency of the oscillator is determined by the ratio of relaxation time and refractory period (R/R). The frequency is also affected by the capacitance values of the external components and the memory device. When the R/R ratio is fixed, and the capacitance values are adjusted, then the oscillator frequency can be adjusted.

The TD-24.576MDD-T oscillator works within a temperature range of -40°C to +70°C. This is because the oscillator is designed to use a reversed bi-stable threshold gate. This type of gate is composed of two transistors, which keep the gate activated even if the supply voltage drops. This is a major advantage of the TD-24.576MDD-T, as it makes the oscillator more resistant to environmental changes, and extends the product’s life cycle.

Conclusion

The TD-24.576MDD-T oscillator is a widely used device, which offers many advantages. It is typically applied in electronically-controlled pulse-width modulation systems and clocks. The oscillator works by alternately releasing and storing pulses of electrical signals. The frequency of the oscillator is determined by the ratio of relaxation time and refractory period. The oscillator is also designed to operate within a temperature range of -40°C to +70°C. This provides excellent operational stability and extends the product’s life-cycle.
