Programmable oscillators are devices that use a combination of hardware and software to generate signal outputs, such as pulses, pulses waves, sine waves and digital frequencies. These oscillators typically allow for more flexibility than conventional, fixed frequency oscillators. An oscillator is characterized by frequency and amplitude. Frequency is typically represented as a number of periods per unit time, while amplitude is typically expressed as the peak-to-peak voltage magnitude of the output waveform.The SIT1602AIE8-25E programmable oscillator provides an output frequency range from 25-8kHz in single-rate use. It is compatible with the industry-standard 8-pin DIP, 8-pin SOIC, 8-pin SSOP, 10-pin TSSOP, 10-pin VSSOP, and 13-pin QFN packages. The oscillator features an operating temperature range of –40°C to +125°C and is available in both lead-free and leaded versions.The SIT1602AIE8-25E programmable oscillator operates based on a PLL (phase-locked loop) based architecture. The PLL is a type of feedback system, which is used to generate signals that are in phase with a reference signal. In the SIT1602AIE8-25E, the reference signal is a quartz crystal oscillator and the output signal is a single rate clock. There are several components involved in the operation of the PLL: input, phase/frequency detector, loop filter, and VCO (Voltage Controlled Oscillator).A phase/frequency detector is an electronic circuit that compares two signals and produces an output signal that depends on their difference in phase and/or frequency. It can be used to phase lock a signal to the phase and frequency of a reference signal.The loop filter is used to smooth out the output of the phase/frequency detector and provide a stable input to the VCO. It typically consists of one or more capacitors, either in series or in parallel.Finally, the VCO is used to determine the output frequency of the oscillator. It is typically based on an LC (inductor-capacitor) circuit which is sensitive to voltage inputs. When a DC voltage is applied to the LC circuit, it stores energy and produces an oscillating output. The VCO is used to adjust the frequency of the output based on the voltage input.The SIT1602AIE8-25E programmable oscillator also features a low phase noise output, flat frequency response, high accuracy and low jitter, making it ideal for a wide range of applications, such as communication systems, N-1 generators, and consumer products. It is also suitable for a wide range of frequencies, from audio frequencies to microwave frequencies.Overall, the SIT1602AIE8-25E programmable oscillator is a versatile and cost-effective solution for a wide range of applications requiring precise and reliable signal outputs. With its adjustable frequency range and low power consumption, it is ideal for applications such as communication systems, N-1 generators, and consumer products. Its low phase noise and flat frequency response make it well-suited for a wide range of frequencies, from audio to microwave frequencies.
