Programmable oscillators serve a myriad of important functions within electronic systems, from providing a timing reference for clocking internal components to defining a radio frequency output. One of the more popular selections, the SIT9005ACL2G-XXDP programmable oscillator, is used in a variety of applications.

The SIT9005ACL2G-XXDP is a dual-output programmable oscillator capable of producing frequencies between 6.25 and 2485 MHz. It operates using CMOS logic, and features eight programmable input pins, resulting in an exceptionally wide range of frequencies. With its low power 0.9V-3.3V input range, the SIT9005ACL2G-XXDP is suitable for mobile and embedded wireless applications.

The SIT9005ACL2G-XXDP is ideal for a wide range of applications requiring both low power and high frequency output. These include communications infrastructure, test and measurement equipment, computer peripherals, satellite television receivers, mobile phones, and other battery-powered devices. This versatile programmable oscillator is capable of producing both fundamental output frequencies as well as accurate harmonic frequencies, giving users additional flexibility when designing circuits.

The reason for the flexibility of the SIT9005ACL2G-XXDP is that it provides two independent outputs, each programmable over an independent frequency range of 2.5-2485MHz. This includes both fundamental output frequencies and accurate harmonic frequencies. Those two outputs can be programmed simultaneously while still being able to maintain very high accuracy, thereby providing designers with a great deal of flexibility in their design. Additionally, a single crystal reference can be used for both outputs, allowing for further savings in cost.

In terms of its working principle, the SIT9005ACL2G-XXDP\'s internal circuit is based on a phase-locked loop (PLL) synthesizer. This PLL synthesizer takes a reference signal from an external crystal, and then uses its internal digital-to-analog converter (DAC) to produce a frequency output that can be programmed to the desired frequency using the eight input pins. This output frequency is then passed through a high-quality dedicated voltage-controlled oscillator (VCO) before being sent to the output pins. This PLL synthesizer system provides a high degree of frequency accuracy, permitting the SIT9005ACL2G-XXDP to maintain a constant phase together with a reference signal.

Thanks to its combination of dual output, high frequency, and low power requirements, the SIT9005ACL2G-XXDP is a reliable and highly regarded programmable oscillator suitable for use in a variety of applications. Its PLL synthesizerbased circuit also provides a consistent frequency accuracy, making it an ideal choice for implementations requiring precision timing. As a result, the SIT9005ACL2G-XXDP is an essential part of many designs in the electronics industry, from communications infrastructure to battery-powered devices.
