Programmable Oscillators

Programmable Oscillators are versatile and adjustable frequency oscillators designed to generate accurate, stable reference frequencies and clock pulses. These oscillators are used in a variety of applications, including embedded microprocessor-based systems, automotive electronics, telecommunications, network control, and medical instrumentation. They offer significant advantages over the traditional quartz crystal oscillators in terms of accuracy and stability, as well as reduced size and power consumption. One example of a programmable oscillator is the SIT9005ACU2H-30EO. This oscillator is a fully-programmable, 1-30MHz voltage-controlled oscillator (VCO) with a wide range of applications. It is designed to operate from a single 3.3V power supply and is configurable up to 30MHz in 1MHz increments. It features an on-chip chopper-stabilized oscillator which provides a low-noise and temperature stable oscillation output. The SIT9005ACU2H-30EO is a highly precise control element that is ideal for controlling frequency in embedded systems. It is an ideal choice for applications requiring precise and stable frequency control, such as microprocessor-based systems, telecommunications, automotive electronics, network control and medical instrumentation. The SIT9005ACU2H-30EO offers a variety of features, including low phase noise and jitter levels, precise tuning voltage linearity, excellent frequency stability over temperature, low power consumption, and a small footprint. The device has an on-board chopper-stabilized oscillator which ensures precise operation over temperature and supply voltage variations. It also offers maximum frequency accuracy of ±0.05% and phase noise of -138 dBc/Hz at 10kHz offset. The SIT9005ACU2H-30EO has a wide frequency tuning range from 3.3V to 9V, and it is configurable in 1MHz steps up to 30MHz. Additionally, the device has configurable output frequency offset and output power supply for operation of a wide range of applications. The working principle of the SIT9005ACU2H-30EO is based on a tuning control feedback loop. The tuning control block, a voltage-controlled oscillator (VCO), is composed of a VCO core and a loop filter which forms a frequency-selective feedback loop. The oscillation frequency of the VCO is controlled by a voltage applied to the tuning control pin. The VCO output is fed back to the loop filter and integrated. The integrated value is then fed to the tuning control input of the VCO, resulting in an accurate and stable oscillation frequency. The SIT9005ACU2H-30EO is a versatile and adjustable frequency oscillator designed to generate accurate, stable reference frequencies and clock pulses. It offers significant advantages over traditional quartz crystal oscillators in terms of accuracy and stability, as well as reduced size and power consumption. With its wide range of features, this oscillator is an ideal choice for embedded systems and other applications requiring precise and stable frequency control.
