Programmable oscillators are a type of oscillator that provides a programmable output frequency. The SIT9005ACA1G-18DG is a commonly used programmable oscillator. It is an oscillator with a PLL (phase-locked loop) that can be programmed to address different frequency needs within a wide range of output frequencies. The oscillator is designed to operate in continuous wave (CW) mode, but can also be programmed into burst mode, allowing for each cycle to be precisely defined.

The SIT9005ACA1G-18DG offers low jitter, high accuracy and high stability outputs ideal for a wide range of applications from telecoms, computing, instrumentation and more. It comes in an industry-standard, 18-pin SOIC package and is available in two temperature grades (TTL, CMOS). The oscillator features a single-output crystal oscillator with a voltage-controlled crystal (VCXO) frequency range of 10 to 80MHz, a TTL frequency range of 4 to 360MHz, and a maximum conversion rate of 300kHz.

The SIT9005ACA1G-18DG has a wide range of application fields. It can be used in the telecoms field from access networks to base stations, as well as in telecoms applications such computer cards, test instruments and consumer electronics. In addition, the oscillator can also be applied in computing fields such as PCs, laptops and servers, instrumentation such as medical instruments and industrial equipment, as well as consumer products such as TVs and radios.

The working principle of the SIT9005ACA1G-18DG is fairly straightforward. It uses an external high frequency crystal to generate an output frequency which is then divided down to the desired frequency by a phase locked loop (PLL). The PLL is then used to precisely control the output frequency of the oscillator by adjusting the voltage level applied to the crystal. The voltage is used to shift the frequency of the output to the desired level as specified by the user. The output frequency is also stable over temperature, power supply and other environmental factors.

Overall, the SIT9005ACA1G-18DG is an excellent choice for a wide range of application fields that require an oscillator with a programmable output frequency and precise control over the output. It is a reliable and affordable oscillator with a wide range of output frequencies, high accuracy and low jitter, making it an ideal choice for many applications.
