Oscillators are components that generate a periodic signal with a time period that is determined by the component itself. SIT8208AC-81-18E-8.192000T is one of them, which is an ultra-precise voltage controlled oscillator (VCO) that has Dual RMS Frequency Stability. This oscillator is designed to have exceptionally low phase noise and great accuracy.

SIT8208AC-81-18E-8.192000T oscillator is widely used in wireless communications, such as GPS, cellular and navigation systems, and can be used in various test and measurement applications. It provides a reliable and cost effective source of timing at speeds up to 802.11ac, as well as high performance clocking for network tracing, memory navigation, video, audio and other full-duplex media applications.

An integrated phase-locked loop (PLL) is incorporated into the SIT8208AC-81-18E-8.192000T oscillator to increase frequency stability and reduce its phase noise. This PLL uses a reference frequency signal and a feedback signal from the oscillator output to keep the oscillating frequency within certain limits. The feedback signal is generated by a negative-resistance network and a low-noise voltage-controlled oscillator (VCO).

Furthermore, the SIT8208AC-81-18E-8.192000T oscillator uses temperature compensation circuitry to minimize temperature-induced frequency shifts. This circuitry uses temperature-sensing diodes to detect temperature changes and then provides frequency corrections accordingly to maintain the frequency within the specified ranges. This temperature compensation helps maintain the accuracy and stability of the oscillator over extended temperature ranges.

In addition, the frequency accuracy of the SIT8208AC-81-18E-8.192000T oscillator can be further improved by trimming the frequency with a programmable digital trimmer. This trimmer allows fine tuning of the frequency to a desired accuracy within the specified range. The trimming will also help to reduce the phase noise.

The SIT8208AC-81-18E-8.192000T oscillator is designed to have very low current consumption and consumes only few mA when in operation. This low current consumption allows it to be used in applications with limited power supplies or battery-operated applications. The oscillator is housed in an 8-lead hermetic package, providing good thermal conductivity and a high degree of protection for the device.

Overall, the SIT8208AC-81-18E-8.192000T oscillator is an ultra-precise VCO with dual RMS frequency stability which is suitable for various applications. Its integrated PLL, temperature compensation circuitry and digital trimmer provide excellent accuracy and stability, while its low current consumption allows it to be used in portable applications.
