The TD-66.667MDD-T is a mid- to high-frequency oscillator, typically operating at 66.667MHz with a duty cycle of 50%.

Application Field

The TD-66.667MDD-T oscillator is suitable for applications requiring precise timing. It can be used in embedded microcontroller applications, digital signal processing applications, industrial equipment, computer peripherals, and medical equipment. In addition, it can be used for frequency control in phase-locked loops, frequency synthesizer, electronic system synthesis, and wideband FM radio receivers.

Working Principle

The working principle of the TD-66.667MDD-T oscillator is based on a quartz resonator, which is a timing component. The oscillator operates with a quartz resonator mounted on a leadframe. The quartz oscillator is a combination of an oscillator circuit and a frequency divider circuit. The frequency divider circuit is used to divide the incoming signal from the input into two equal parts, which are then used to calculate the output frequency of the oscillator.The quartz oscillator is designed such that its frequency does not vary over a range of temperatures. This is due to the fact that the frequency of the quartz resonator is determined by its physical properties. The resonator is usually encased in a hermetically sealed package to protect from environmental factors that could cause a shift in frequency.The output frequency of the oscillator is determined by the frequency of the quartz resonator. The oscillator’s output is then equal to the frequency of the resonator divided by the frequency divider circuit. The frequency divider circuit consists of two 12-bit counters with an adjustable pulse width.The TD-66.667MDD-T oscillator is usually powered by a 5V DC power supply. The oscillator has an operating temperature range of 0°C to 70°C and a frequency stability of ±30ppm.

Conclusion

The TD-66.667MDD-T is a mid- to high-frequency, precision quartz oscillator that is suitable for timing applications and can be used in a variety of embedded microcontroller and digital signal processing applications. It works on the principle that a quartz resonator and frequency divider circuits is used to determine the output frequency of the oscillator. The oscillator can operate over a temperature range of 0°C to 70°C and has a frequency stability of ±30ppm.
