Working Principle

The SIT8208AC-GF-25S-62.500000X is an adaptive oscillator that uses velocity feedback loops and phase lock-loop circuitry to maintain a frequency output with extremely low phase noise and fast phase lock-in time. It utilizes a precision timebase, providing accurate frequency and excellent temperature stability.The device contains an oscillator core consisting of a temperature-compensated oscillator (TCXO), an oscillator feedback circuit, and an amplifier. The frequency programmability is achieved by varying the gain of the amplifier, which in turn adjusts the oscillator’s frequency. The output of the oscillator is then sent to a phase locked loop (PLL) circuit which acts as a frequency synthesizer that can be programmed to generate any frequency between 1MHz and 200MHz. The PLL also helps reduce the noise of the oscillator.The SIT8208AC-GF-25S-62.500000X is powered by an on-board voltage regulator, an on-board EPROM memory, and a programmable crystal oscillator. The on-board EPROM stores the frequency and phase settings, providing the ability to quickly switch between different frequencies and/or phase settings.
