Working Principle

The SIT8208AI-G2-18S-19.200000T consists of an in-phase/quadrature (I/Q) silicon oscillator die, described as a differential QIE (Quadrature Frequency and Amplifier Dialer). The die contains a voltage controlled oscillator (VCO), with an associated bank of tuneable LC tanks together with logic blocks to generate the output frequencies. The quartz crystal oscillator and the VCO are tuned to the required frequency and the output PLL/VCO frequency is determined by the tuning range of the on-chip VCO and the external crystal oscillator.

The crystal maintains the oscillation frequency and provides the inherent temperature stability for the oscillator.The output of the oscillator is maintained by the heat-sink feedback and the combination of the tuning range of the on-chip VCO and the external oscillator. The SIT8208AI-G2-18S-19.200000T also employs a special trim circuit with EEPROM memory for accurate fine-tuning.

In addition, this oscillator offers automatic frequency compensation to the thermal environment and eliminates the need for additional thermal compensation circuitry. This eliminates the need for additional trimming or programming to reduce frequency drift over temperature and humid environments. The SIT8208AI-G2-18S-19.200000T provides integrated EMI protection, allowing reliable operation in harsh electromagnetic-interference prone environments.
