Programmable oscillators are a type of circuit component in which the frequency of a digital signal output by the oscillator can be programmed or varied electronically. The most common type is a voltage-controlled oscillator (VCO), but other types of programmable oscillators include programmable delay elements and frequency synthesizers.The SIT9005ACF1H-30NA is a programmable oscillator manufactured by Silicon Standard. This oscillator offers tuning range of 0.2 to 18 MHz and logic compatibility with clock speeds of up to 60 MHz. It features low power consumption (30mA max) and is available in a standard 8-lead PLCC package.The SIT9005ACF1H-30NA is designed for various industrial and consumer applications, including clock distribution boards, personal computers, automotive electronics, and medical equipment. It can also be used in RF and communications systems as well as industrial control systems.The working principle of the SIT9005ACF1H-30NA programmable oscillator involves the use of a voltage-controlled crystal oscillator (VCXO). This oscillator consists of a tuned LC (inductor and capacitor) circuit connected to a piezoelectric material such as quartz. When a voltage is applied to the crystal, the crystal will vibrate at a specific frequency.This frequency can be varied by changing the applied voltage, thus making the oscillator a programmable or tunable device. The oscillator uses a voltage-controlled voltage source (VVCS) to control the output frequency. The VVCS is made up of two components: a voltage-controlled current source (VCCS) and a voltage-controlled resistance (VCR).The voltage-controlled current source is designed to provide a precise current level to the VCXO. It is connected to the output stage of the oscillator, which is responsible for the tuning range of the oscillator. The voltage-controlled resistance is used to set the minimum frequency of the VCXO. The output frequency of the SIT9005ACF1H-30NA can be programmed via an external potentiometer or a software interface.The SIT9005ACF1H-30NA is a highly reliable programmable oscillator for industrial, medical, and consumer applications. It offers wide frequency range and low power consumption, making it an ideal choice for designers looking for a robust and cost-effective programmable oscillator solution.
