Programmable Timers and Oscillators

Programmable timers and oscillators are electronic devices that generate either a signal with a specific frequency, or they can measure and/or control a signal with a specific frequency. They are usually used to control machines or components that require precision timing, such as digital frequency synthesizers and digital clocks. The 8N3SV75AC-0168CDI is an example of a programmable timer/oscillator.

Application Fields

The 8N3SV75AC-0168CDI can be used in a variety of applications, such as in clock and timing circuit designs that require a variable frequency source, phase-locked loop (PLL) circuit designs that require a variable frequency reference clock, and embedded applications. It can also be used as a voltage-controlled oscillator for generat-ing adjustable signals.

The 8N3SV75AC-0168CDI can also be used in wireless communication systems to control the output of the modulation system, providing precise modulation timing and low jitter performance. Additionally, it can be used in serial data communication systems such as RS-232 and IEEE 488, as well as in telecommunications networks, for clock and timing control.

Working Principle

The 8N3SV75AC-0168CDI uses a multi-stage voltage-controlled oscillator (VCO) to generate an output signal with a frequency that is determined by the voltage applied to the control input. The 8N3SV75AC-0168CDI operates in two modes, pulse width modulation (PWM) and pulse position modulation (PPM), and it can be programmed via a serial interface. In PWM mode, the 8N3SV75AC-0168CDI can be used to generate pulses with adjustable widths, while in PPM mode, it can be used to generate pulses with adjustable positions.

The 8N3SV75AC-0168CDI also features an adjustable voltage-controlled slop, which can be used to fine-tune the frequency of the output signal. The adjustable slope is achieved by varying the gate width of the slop generating circuit, so that the frequency depends on the voltage applied to the gate.

The 8N3SV75AC-0168CDI also features an adjustable output phase-shift, which allows the phase-shift of the output signal to be adjusted in order to achieve a more precise frequency. The adjustable phase-shift is achieved by varying the capacitance of the phase-shift generating circuit, which affects the output frequency of the device.

Overall, the 8N3SV75AC-0168CDI is a versatile, programmable timer/oscillator that can be used for a variety of applications requiring precise timing control. Its adjustable voltage-controlled VCO and adjustable output phase-shift make it ideal for applications requiring fine-tuning of the frequency and phase of the output signal.
