Oscillators

An oscillator, or clock generator, is a device that produces a periodic signal on its output. These periodic signals are used to control the speed and frequency of devices like microprocessors and digital logic. The specific oscillator discussed in this article is the SIT1602BC-12-XXS-33.333330G.

The SIT1602BC oscillator is designed to provide an ultra-low jitter output signal over a wide frequency range. The device is capable of operating over a 2.5 V to 3.3 V power supply range and can provide frequencies ranging from 40 MHz to 333.333 MHz. The device is packaged in a miniature 12-pin TSSOP package, making it an excellent choice for space constrained applications.

The SIT1602BC oscillator utilizes a Pierce oscillator circuit to provide a highly stable output signal. This type of oscillator is based on the astable multivibrator circuit and uses two capacitively-coupled inverters as the active components. The periodic oscillations are generated by a signal being recirculated through the linear chain of two inverters. This recirculated signal will build up until the inverter at the end of the chain trips and changes back to its initial state. This process then continues until the oscillations die out.

The SIT1602BC uses the Pierce oscillator to provide a highly accurate clock signal. The device includes an on-chip trimming resistor to adjust the frequency accuracy so that it can be tuned with as high as ±50 ppm over temperature and voltage ranges. The device also features a 10 µA low supply current, making it an ideal choice for low power designs. Additionally, it offers a high frequency output enable/disable control, making it a versatile and useful component for a wide variety of applications.
