Programmable oscillators, or POs, are devices that offer variable frequency and duty cycle. They can offer timing precision, better accuracy, temperature stability, low distortion, excellent jitter, and a wide frequency range. The SIT9005ACU1G-18DI is one such device.

The SIT9005ACU1G-18DI is a single-channel programmable oscillator that has an operating temperature range of -40°C to +125°C. It offers a frequency range of 8 MHz to 8.3 GHz with accuracy of ±100 ppm. This device also offers an output phase noise of -108 dBc/Hz at 1 GHz. It has an 18-bit binary resolution which allows for higher frequency accuracy and higher resolution than POs with less than 18 bits.

This device also features 18 digital input pins and can be programmed via a serial interface-like I2C. It offers excellent reliability due to its CMOS technology. It is extremely low power with a supply voltage ranging between 1.8V to 3.3V. In addition, the SIT9005ACU1G-18DI has a wide variety of application fields such as RF or microwave test systems, digital television, and communications systems.

The working principle of the SIT9005ACU1G-18DI is based on a digital-controlled oscillator (DCO). The DCO is essentially a voltage-controlled oscillator (VCO) but it is digitally controlled by an external source. It is programmed using digital signals and an external clock source. It is a highly versatile device, as it can be used for a wide range of applications, from low-frequency to microwave frequencies.

The SIT9005ACU1G-18DI is an ideal choice for applications requiring high accuracy and stability, such as fixed-frequency applications, frequency hopping, and frequency synthesizers. It offers superior jitter performance and low harmonic distortion, making it suitable for applications such as broadband modulators, local loop transceivers, satellite receivers, and mobile transmitters.

The SIT9005ACU1G-18DI is a reliable, cost-effective, and efficient programmable oscillator, ideal for applications in the RF and microwave industry. It offers higher accuracy than other programmable oscillators, while also featuring an 18-bit binary resolution and digital control pins. It offers all the benefits of a modern programmable oscillator, making it a popular choice among engineers and hobbyists alike.
