Oscillators - DSC1003DL2-148.5000T

Oscillators are essential components in the electronics world and are used in many electronic circuits. The DSC1003DL2-148.5000T is a voltage-controlled-crystal oscillator (VCXO) that provides good frequency and phase noise performance in a small package.The DSC1003DL2-148.5000T is a compact 3.3V oscillator designed for networks, broadcast, and precision measurement applications. The device operates with a pullability of ±100ppm from a crystal-controlled oscillator over a frequency range of 148.5000MHz - 149.4937MHz. The operating temperature range is from -40°C to +85°C with tight output jitter control of 150fs (typ). The device features a 10 ns settling time, low insertion loss and excellent phase noise of -142dBc/Hz at 10kHz offset from carrier.The DSC1003DL2-148.5000T is a very versatile oscillator. It can be used for a wide range of applications in the frequency range of 148.5000MHz to 149.4937MHz. It is particularly suited for applications that require precise and low-jitter reference clocks, such as in digital telecommunications networks, broadcast systems, and precision measurement instruments.The device works on the principle of voltage-controlled crystal oscillators. A voltage-controlled-crystal oscillator (VCXO) is a form of oscillator in which an external voltage applied to the oscillator crystal is used as a way of controlling the frequency of an electronic signal. VCXOs are designed to provide an adjustable frequency reference that is both stable and accurate.The DSC1003DL2-148.5000T VCXO uses a quartz crystal as the frequency determining element. The device uses a tuning varactor diode to vary the capacitance in direct proportion to an applied bias voltage. This voltage is used to control the oscillator frequency around the nominal center frequency, i.e., 148.5000MHz. The tuning range remains constant regardless of operating temperature and supply voltage variations.The VCXO also features a wide tuning range. This allows for greater flexibility in setting the necessary output frequency. There are several factors that influence the device’s tuning range such as the type of crystal, the crystal trim capacitance value, and the size of the varactors used in the design.The DSC1003DL2-148.5000T also features low noise performance and a wide operating temperature range. The low jitter performance is ideal for various applications such as data networking, broadcast systems, ATE, military and medical systems. The device also offers excellent phase noise performance for superior system performance.In conclusion, the DSC1003DL2-148.5000T is a versatile, high-performance oscillator with a wide frequency range and excellent frequency and phase noise performance. Its small form factor and low jitter performance make it suitable for a variety of applications.
