CPPFXC8-A7BR-40.96TS application field and working principle

Oscillators are the basic components of electronic circuits. They can generate a continuous sine wave without the need for external power supply. CPFFC8-A7BR-40.96TS is an oscillator that can provide output frequency from 40.96 to 62.535MHz. It is widely used in oscilloscope, frequency counting and so forth.

The CPFFC8-A7BR-40.96TS oscillator is a temperature-compensated integrated circuit; its output frequency is mainly determined by the temperature-compensated crystal (TCXO) on the chip. The TCXO on it uses advanced patented temperature compensation technology to ensure its stability. In addition, the chip also has two additional control signals (3V and 5.7V inputs) to adjust frequency, which makes it possible to achieve better temperature characteristics and frequency stability.

When the voltage on the V+ pin is within the allowable range, the oscillator will work normally when there is an external crystal in the chip. The frequency is determined by the external crystal oscillator. The oscillator internal circuit consists of a voltage divider, a Schmitt trigger, and an internal amplifier.The alternating signal of frequency determined by the external crystal is connected to theSchmitt trigger, and theSchmitt trigger will make its output as high or low as a positive or negative logic signal, and then the Schmitt logic signal is amplified by the amplifier and output through the out pin.

In conclusion, CPFFC8-A7BR-40.96TS is a temperature-compensated integrated oscillator, which can provide output frequency from 40.96 to 62.535MHz, and its output frequency is mainly determined by the temperature-compensated crystal (TCXO) on the chip. Its internal circuit consists of a voltage divider, a Schmitt trigger, and an internal amplifier. It is widely used in oscilloscope, frequency counting and so forth.
