Programmable Oscillators

Programmable oscillators are specially designed devices that allow circuit designers to precisely tune the frequency of an oscillation. This tuning capability is useful in developing a wide range of circuits, from simple communications links to sophisticated motion control applications. A programmable oscillator consists of an adjustable oscillating circuit, which generates a signal at the desired frequency, and a controller that sets the parameters of the oscillating circuit.The 511RBA-BAAG is a programmable oscillator developed by Signetics. This device is a highly accurate, wide band programmable oscillator that offers low noise and phase noise, while being robust enough to operate reliably over temperature and voltage changes. The 511RBA-BAAG is specifically designed to replace quartz crystals in precision oscillator applications that require a very stable frequency.The 511RBA-BAAG is a CMOS integrated circuit that supports a wide range of frequencies, from tens of kilohertz to hundreds of megahertz. Its circuit design is based on the popular five-stage Johnson counter oscillator, which allows the oscillation frequency to be programmed via an external clock signal. The 511RBA-BAAG also incorporates an adjustable voltage-controlled crystal oscillator (VCXO) network for additional frequency stability.The 511RBA-BAAG has two different operating modes: open loop and closed loop. In open loop mode, the device operates as an independent oscillator. The frequency of oscillation is determined by the clock signal and the voltage-controlled crystal oscillator (VCXO). In closed loop mode, the device operates as a voltage-controlled oscillator (VCO). The output frequency can be adjusted by varying the supply voltage. The 511RBA-BAAG also provides several features that make it ideal for use in precision oscillator applications. It offers excellent frequency accuracy, low noise and phase noise, wide temperature compensation range, and an integrated temperature sensor that provides an accurate temperature-compensated frequency reference. The 511RBA-BAAG is an ideal solution for applications requiring a stable frequency reference with excellent accuracy and low noise. Its high performance and low power consumption make it ideal for a variety of applications, including communications links, motion control, precision timing, and instrumentation. It can also be used as a reference oscillator for generating stable, accurate signal sources. With its reliability and ease of use, the 511RBA-BAAG is a great choice for designing precision oscillators.
