Oscillators, or oscillating devices, are components that produce a sine wave, pulse wave, or other shaped waveforms at a specific frequency. SIT9120AC-2B1-25E166.660000G is an oscillator built specifically to provide reliable, accurate, and most suitable solution for your precise timing and synchronization needs.

Application Field

The SIT9120AC-2B1-25E166.660000G is suitable for applications in the industrial process control, medical imaging, communications, computing, and system-level clock distribution. It is capable of sustaining robust communications in industrial and enterprise networks and offers accurate timing for synchronisation in traditional and distributed systems. As a compact reference clock module, it provides highly stable and precise timing reference for multi-channel synchronous transport systems, wireless communication systems, and PON systems. Other potential applications include systems requiring high-precision clocking and/or jitter control.

Working Principle

The SIT9120AC-2B1-25E166.660000G oscillator utilizes a PLL-VCXO (voltage controlled crystal oscillator) to control frequency, temperature and aging, into which an external reference is input. The working principle of the oscillator is as follows: The PLL-VCXO receives the input reference, and the crystal oscillates at its own frequency. The oscillator then uses a frequency dividing circuit to divide down the reference frequency. The output signal then enters the synthesizer circuit and they use the phase comparison technique to generate a precise output frequency that can achieve the target frequency with accuracy better than a few parts in one million. The synthesizer circuit then outputs two signals, one to control the oscillation frequency of the VCXO, and the other to output the output frequency.

Although the PLL-VCXO has an analog phase control, the output frequency can be accurately controlled in a digital manner, and since the output frequency is not affected by the environment and the power supply, a highly precise frequency can be output.

The SIT9120AC-2B1-25E166.660000G oscillator also uses advanced digital temperature compensated calibration circuit (DTCXO) technology to optimize the balance between jitter performance, power consumption and startup time.

It is able to achieve frequency accuracy of 10 ppb (parts per billion) at 25°C, and the ultimate precision is 1.4 ppm (parts per million). The SIT9120AC-2B1-25E166.660000G offers a wide range of supply voltages from 1.2 V to 3.8 V and a current consumption of 11 mA, making it an ideal choice for applications in monitoring and controlling of industrial processes. The phase noise low-end noise floor is -150 dBC, while the jitter is 5 ps peak-to peak at 166.66MHz.

The SIT9120AC-2B1-25E166.660000G is a highly suitable and reliable solution for applications that require precision timing and synchronization accuracy. By using its advanced DTCXO and PLL-VCXO technology, it is able to deliver an output frequency of 166. 66MHz with a frequency accuracy of 10 parts per billion and a low jitter of 5 picoseconds peak-to-peak at 166.66 MHz.
