Working Principle

The TA-70.000MDD-T is a Voltage Controlled Oscillator (VCO). It works by deriving its output frequency from an input voltage, which can be controlled by an external voltage controller. The output frequency is directly proportional to the input voltage. The device consists of three stages — a first stage, a second stage and a third (final) stage.

The first and second stages are both AC coupled voltage controlled oscillator circuits, while the third stage acts as an amplifier. The two AC coupled stages allow the device to achieve very high-frequency stability and significantly reduce the amount of frequency drift due to temperature variations. A wide range of control voltage can be applied to the device to achieve a range of frequencies.

The TA-70.000MDD-T offers exceptional stability over time and temperature. This stability is achieved by using an enhanced temperature compensation circuit, which senses temperature and adjusts the oscillator frequency accordingly. The device also uses a very low-noise output stage, and is designed to reduce the amount of jitter in the output signal.

The TA-70.000MDD-T is a robust and reliable device capable of operating over a wide temperature range. It is an ideal choice for high-frequency applications requiring precise timing and glitch-free performance. The device is compact and has a low profile, making it easy to integrate into existing systems.
