It is especially suitable for wireless communication systems, such as GSM, CDMA, WCDMA, and other wireless communication systems. It can also be used in navigation systems, including the Global Positioning System (GPS), the BeiDou navigation system and other navigation systems. In addition, it is ideal for high speed data transmission systems, such as LAN, WLAN and other data transmission systems.

Working Principle of CFV-20675000DZFB

The CFV-20675000DZFB TCXO is a temperature compensated oscillator based on a quartz crystal. The quartz crystal is placed between two electrodes and a voltage is applied across the crystal. When the voltage is applied, the crystal vibrates at a specific frequency and sends an electrical signal to the circuit, which is then transferred to an output. The frequency of the signal output from the oscillator is determined by the frequency of vibration of the crystal.

The CFV-20675000DZFB chip uses a temperature compensation system to adjust the oscillator frequency and maintain a stable output over a wide temperature range. This temperature compensation system consists of a temperature sensor, a controller, and a frequency-control element. The temperature sensor detects the ambient temperature and sends a signal to the controller. The controller then adjusts the signal applied to the frequency-control element which subsequently adjusts the frequency of the oscillator signal and keeps it constant, even if the ambient temperature changes.

In summary, the CFV-20675000DZFB TCXO is a temperature compensated crystal oscillator with a wide frequency range, good phase jitter, low power consumption and small pin-package design. It is widely used in the fields of wireless communication, navigation and data transmission systems. And its working principle is based on a temperature compensation system which uses a temperature sensor, a controller, and a frequency-control element to maintain the oscillator frequency at a constant level even when the ambient temperature changes.
