Programmable Oscillators

Programmable oscillators are electronic components that are used to help stabilize output signals on electronic equipment or electrical systems. These components can help stop fluctuations that can cause errors in program execution or result in the system not operating in variable conditions. One example of a programmable oscillator is SIT1602AIR7-25S. This type of component has a wide range of applications and is made to operate over a wide range of frequencies. Its ability to vary its frequency makes it useful for setting timing functions on equipment, such as frequency synthesizers, digital to analog converters, and time division multiplexers. The SIT1602AIR7-25S programmable oscillator is designed to operate up to 25MHz and comes in a 16-pin Quad Flat No-Lead package. It utilizes CMOS Technology which ensures its low power consumption and very small surface area. It operates at a very low power, making it suitable for battery-powered equipment. This makes it most useful for portable and consumer electronics devices. Additionally, this type of programmable oscillator has the ability to keep a stable signal when it changes to the different frequencies. To properly function the SIT1602AIR7-25S programmable oscillator is designed with an input terminal where the logic level waveforms can be provided. It then amplifies the waveform with a built in amplifier and an input resistance, allowing the signal to be adjusted from 0.1V to 1.2V of amplitude. This oscillator uses a 20-bit register for frequency configuration. The frequency range for the SIT1602AIR7-25S oscillator can be adjusted by changing the length of the waveform. The waveform is generated by feedback loops, providing an output waveform that is one-half of the period of the fundamental waveform. The waveform is then stored in the register and accessed to generate the desired frequency in the output signal. The SIT1602AIR7-25S programmable oscillator has the ability to produce an output signal with a standby current of 0.9mA at 25MHz and 0.7mA at 10MHz. This also has the capability of providing an output power of 2.5mW at 25MHz and 1.5mW at 10MHz. With inputs provided to the logic terminal, it will produce a logic power of 4mW at 25MHz and 3mW at 10MHz. With its ability to cycle through the frequencies, the SIT1602AIR7-25S programmable oscillator is able to provide reliable and stable signals for applications needing a wide range of frequencies. This makes them ideal for applications in consumer electronics that require a reliable signal for functions such as time division multiplexing, frequency synthesizers, and digital to analog converters. This also makes them quite useful in portable equipment, as they have a low power over the wide range of frequencies they support.
