Programmable oscillators provide a versatile and cost-effective solution for frequency synthesis and control in applications ranging from home entertainment systems to medical imaging systems. One such example is the SIT1602ACA2-18S, a Programmable Oscillator that combines high frequency accuracy and a wide range of frequencies in a convenient, low-power package.

The SIT1602ACA2-18S utilizes a Programmable Oscillator design based on a voltage-controlled crystal oscillator (VCXO) to offer fixed frequencies from 18 to 26.37 MHz, depending on the processor used, as well as a frequency tunability of ±2.5 ppm over its operating temperature range. The device utilizes two logic inputs that allow the user to externally control the frequency by changing the logic signal from either TTL or CMOS compatible logic levels.

The control voltage of the SIT1602ACA2-18S is adjusted by a precision finely-tunable resistor, or potentiometer, depending on the application requirements. One of the design features that makes this programmable oscillator so attractive is its extremely small package size, allowing it to be mounted to a variety of circuit boards with ease and convenience. Low power consumption and minimal system components also minimize board and system costs.

One of the most important features of the SIT1602ACA2-18S is its high frequency stability and accuracy. Featuring a jitter of less than 12ps, the device is able to maintain a delta F (RF) of less than one part per million over the range of temperatures from -40°C to +85°C. Additionally, the device\'s frequency temperature sensitivities and temperature coefficient of frequency (TCF) values ensure that the device is able to maintain frequency accuracy over a wide range of changing temperatures.

The SIT1602ACA2-18S is suitable for applications in the industrial, telecommunications, and medical fields where the device\'s low cost and high performance yields the best overall performance and ROI. As the demand for frequency control and frequency synthesis in applications continues to grow, so does the use of programmable oscillators such as the SIT1602ACA2-18S.

In conclusion, the SIT1602ACA2-18S is ideal for applications that require frequency within the range of 18 to 26.37 MHz, a highly stable frequency with a jitter of less than 12ps, and a low cost, low power packages. Its external logic control input and adjustable control voltage, combined with an extremely small package size and minimal system components, make it an attractive, cost-effective choice.
