Programmable Oscillators

A programmable oscillator is an electronic device that allows for the user to program their waveform, frequency, and other characteristics. These oscillators are typically used for various type of applications such as timing and frequency control, radio wave or signal filtering, or even sensing and detection applications. One such device is the SIT8008BCR8-18N. This oscillator is an integrated circuit that is designed to offer simple, reliable and cost efficient timing solutions.

The SIT8008BCR8-18N oscillator is a low power and wide range of programmable oscillator Ideally designed for power-sensitive applications. The SIT8008BCR8-18N is available in a wide range of package sizes, in three temperature grades, and different frequencies depending on the requirements of the user. It has an input resolution of 1Hz and an internal accuracy of 0.75%. The output signal has a maximum signal swing of 0.5V and it operates over-temperature up to 85°C.

The SIT8008BCR8-18N application field encompasses various applications such as PC motherboards, networking applications, industrial controls, automotive, and automotive immobilizers.

The SIT8008BCR8-18N is designed as a single-chip programmable oscillator and utilizes a ring oscillator architecture. It operates off a low voltage, with current consumption as low as 4mA. It also does not require an external quartz oscillator or resonator.

The device uses a single-track open-loop control architecture with two control nodes. These nodes are used to control the amplitude and the frequency of the output signal. The control nodes consist of two comparators, an amplitude trap, and a frequency attenuator. By controlling these two control nodes, the frequency, amplitude, and other parameters of the output signal can be adjusted.

The SIT8008BCR8-18N also incorporates a programmable crystal oscillator frequency-calibration feature. This feature allows for a user to calibrate their device without the need for an external oscilloscope or expensive tools. The calibration feature works by measuring the on-chip crystal frequency load capacitance and automatically calibrating the device to the correct frequency.

In addition to these features, the SIT8008BCR8-18N also features adjustable slew rate and switching frequency, an integrated power-save circuit, a programmable output-enable level, and a programmable output duty cycle. All these features combine to make the SIT8008BCR8-18N a highly versatile programmable oscillator.

In conclusion, the SIT8008BCR8-18N is an integrated programmable oscillator packed with features including low power consumption, wide frequency range, adjustable slew rate and switching frequency, integrated power-save circuit, and programmable output-enable level. It is ideal for applications such as PC motherboards, networking applications, industrial controls, automotive, and automotive immobilizers. It is also great for use in direct digital synthesizer driven systems, clock generator circuits, and low power and wide range timer/counter applications.
