Programmable Oscillators are oscillators that can be adjusted to operate at frequencies and voltage levels specified in an application. They are used when an application requires an adjustable frequency to varying conditions. Such oscillators work in true-synchronous mode and operate over wide temperature ranges. The SIT9005ACR1G-18EB is an example of such a programmable oscillator that has recently been developed by Vectron International.

SIT9005ACR1G-18EB Application Field

The SIT9005ACR1G-18EB is a programmable oscillator that is especially suited for use in applications where reliable, low jitter performance is required over a wide temperature range. This device is ideal for communications systems, Ethernet switches, Personal Digital Assistants (PDAs), Global Positioning System (GPS) receivers, and other related applications. The SMBus serial interface allows for simple programming and flexibility.

The SIT9005ACR1G-18EB offers a range of adjustable frequencies from 500 kHz to 2.2GHz, with operating temperature range of -40°C to +100°C. It also provides variable output voltage range up to +3.3V and is designed to operate over a wide range of input voltages. All of these features make SIT9005ACR1G-18EB well-suited for a range of applications.

Working Principle

The SIT9005ACR1G-18EB works on the same principle as other programmable oscillators, but with a few notable differences. The device is integrated with an ultra-low jitter phase-locked loop (PLL) for reliable operation. The PLL helps to minimize output jitter at an adjustable frequency range of 250 to 2.2GHz. The frequency of the oscillator is controlled by an internal oscillator, and the output frequency is adjustable by programming the oscillator\'s frequency directly or by writing frequency registers in the PLL\'s configuration registers.

The SIT9005ACR1G-18EB has a fast start-up time of less than 250ns, which makes it ideal for applications that require fast switching. This device features a wide range of selectable output levels from 0.8V to 3.3V, and its serial peripheral interface (SPI) also enables users to program and monitor the oscillator\'s frequency and power supply conditions.

Conclusion

The SIT9005ACR1G-18EB is a highly reliable programmable oscillator that is well-suited for use in a variety of applications. The device offers an adjustable frequency range that is well suited for communications systems, Ethernet switches, PDAs, and GPS receivers. Additionally, its fast start-up time and SPI compatibility make it an attractive option for a wide range of applications that require variable output level and reliable operation over a wide temperature range. This product is an excellent option for any application that requires adjustable frequency and wide temperature range.
