Oscillators are a type of electronic component that generate a periodic electrical signal. 637V156J6C2T is a particular type of oscillator known as a voltage-controlled crystal oscillator (VCXO). It is a frequency-controlled oscillator, meaning its frequency can be adjusted or “tuned” with an applied electrical signal. This type of oscillator is particularly useful in electronic devices and systems that require highly accurate frequency control, such as in wireless communication, radar, and medical equipment.

The 637V156J6C2T is designed for use in applications with stringent frequency performance such as networking, telecommunication, and instrumentation. VCXOs use an AT-cut quartz crystal as the resonator element and a voltage variable varactor diode to control the frequency of the oscillator. The VCXO senses the control voltage applied, and adjusts the frequency of oscillation accordingly.

The 637V156J6C2T has an output frequency range of 24 to 156 MHz and an operating voltage of 3.3V. It is available in three standard package sizes and can drive a load of up to 50 pF. The stability of the frequency for the whole device is ±10 ppm over a temperature range of -40°C to +85°C. It also has excellent phase noise performance of -154 dBc/Hz at 10 KHz offset. It consumes only 1.6mA of current.

In addition, the 637V156J6C2T has an internal 50KOhm resistor connected in series with the input voltage. This improves the device’s stability for faster loop settling, which is important for systems that require precise timing or control loop gain calculations. The device also includes an enable/disable control option, allowing it to be easily disabled and enabled to conserve power or for testing purposes.

The 637V156J6C2T is easy to integrate into any number of systems due to its wide range of output frequencies, low power consumption, and excellent frequency stability. Its features make it an ideal solution for applications that require precise timing and frequency control such as networking, instrumentation, and telecommunication. It enables devices and systems to operate accurately and efficiently, allowing them to meet the demands of the most advanced modern electronic devices.
