Introduction: LFTCXO007009BULK

The LFTCXO007009BULK is an HCMOS type Frequency-Locking Voltage-Controlled Oscillator (FCVCXO) suitable for next-generation telecom and datacom systems. It utilizes a precise voltage-controlled oscillator (VCXO) to ensure ultra-low jitter and high reliability for applications in mission-critical environments. The frequency-lock feature greatly enhances the jitter performance of the oscillator by preventing any out-of-band shifts that would otherwise cause jitter.

Application

The LFTCXO007009BULK is widely used in next-generation telecom and datacom systems. With its frequency-lock feature, it reduces jitter thereby allowing for more accurate and reliable communication. It is suitable for mission-critical communication applications such as in-flight communication, communication on ships and in remote locations, etc. It is also used for frequency synthesizers and other applications that require ultra-low jitter.

Working Principle

The LFTCXO007009BULK is composed of a resonator, a voltage-controlled oscillator (VCXO), and a low-noise amplifier (LNA). The VCXO is the main component of the oscillator. It contains an oscillator section and a frequency-lock circuitry connected to the output of the resonator. It produces an output frequency that is proportional to the input voltage. The frequency-lock circuitry includes a frequency detector and a voltage regulator. The detector detects changes in the output frequency of the resonator and uses a voltage regulator to adjust the output voltage of the VCXO so that the output frequency is brought back to its locked value.

Conclusion

The LFTCXO007009BULK is an HCMOS type Frequency-Locking VCXO suitable for mission-critical applications in telecom and datacom systems. Its frequency-lock feature makes it an ideal choice for applications requiring ultra-low jitter. The working principle of the VCXO is based on the use of a resonator, a VCXO, and an LNA. By detecting changes in the output frequency of the resonator and adjusting the output voltage of the VCXO, the frequency-lock circuitry keeps the output frequency locked at its desired value at all times.
