Programmable oscillators are defined as controllable frequency sources that rely on a microprocessor to configure their waveforms, timing and output frequencies. They are used in applications that require precision tuning to optimize performance. SIT1602BCB7-25E is a precision temperature compensated crystal oscillator (TCXO) that provides low phase noise when operating at a frequency range of 25MHz to 160MHz. It is ideal for frequency control and timing applications with stringent phase noise requirements.

The SIT1602BCB7-25E has a low-power consumption of 2.8mW at a supply voltage of 3.3V and a smaller size of 9.4mm by 10.4mm. It is designed to have a very low phase noise over a broad frequency range, with a noise level of -140dBc/Hz at 10kHz offset and tuning sensitivity of 0.1ppm/°C. It is precision temperature compensated by integration of a temperature sensor, matched resonator and on board electronics. This results in a precise frequency output that is very stable over a broad temperature range (-40 °C to +85 °C). In addition, the SIT1602BCB7-25E offers an export control range of 140MHz, a supply voltage range of 2.3V to 3.3V, 40mA maximum current consumption, an output load of 50Ω, 16pF, and a typical pull range of ±3ppm.

The SIT1602BCB7-25E oscillator is an ideal choice for applications that require high performance, low power consumption, precision timing and frequency control such as wireless communication, test and measurement, high frequency data transmission and radio frequency applications. It can also be used in base station applications, IoT applications, portable medical electronics and consumer electronics.

The working principle of the SIT1602BCB7-25E is based on the crystals used in the oscillator. When connected to an electrical circuit, the crystal will exhibit mechanical resonance properties, meaning it will vibrate at a certain frequency. This frequency is determined by the physical dimensions and mass of the crystal, and is known as the resonant frequency. The resonant frequency is determined by the series, parallel or hybrid configuration of the crystal, which are affected by materials used for construction, type of structure and housing.

The SIT1602BCB7-25E oscillator consists of a temperature-sensitive crystal mounted on a temperature-compensating support. An electronic circuit senses temperature changes and adjusts the oscillator’s output frequency to maintain a constant and precise frequency of 25MHz to 160MHz over a wide range of temperatures.

The oscillator also uses feedback circuitry to apply a fine-tuning signal to the crystal, in order to bring its frequency to the desired value and keep it there. The SIT1602BCB7-25E with its on-board temperature compensation ensures a robust, precise and stable frequency that is free from temperature related variations.

In conclusion, the SIT1602BCB7-25E is an ideal choice for applications that require precision tuning and frequency control. Its precision temperature compensation allows for a constant and stable frequency output over a wide temperature range, making it suitable for a variety of applications.
