Programmable Oscillators are devices developed to assist in electronic system applications where precision timing is important. They are specifically designed to generate a precise frequency, period, or pulse width from a given input. SG-8003CG-PEL is a programmable oscillator developed by SEI Company for high precision timing application.

SG-8003CG-PEL has a wide range of possible uses. It can be used to control precision timing in applications such as telecommunications, automotive, medical, and other applications that require precision timing. It can also be used in frequency-shift keying modulators and demodulators, frequency synthesisers, spread spectrum communicators, VCOs, and PLL synthesizers. The output frequency of the SG-8003CG-PEL can be programmed digitally or externally with a parallel or by an I2C bus, depending on the model. The output frequency can be fine-tuned with an analog adjust pin.

The working principle of the SG-8003CG-PEL is based on a triple-modulus prescaler and a phase comparator. The prescaler divides the incoming signal by a certain factor and the phase comparator compares the incoming signal to the divided signal. The output frequency is thus modulated by the prescaler, the phase comparator and the reference resistor frequency. The output frequency can be adjusted by changing the reference resistor frequency value or the division factor.

The SG-8003CG-PEL also features temperature compensation and power supply rejection, making it suitable for use in a wide range of temperatures and voltage variations. The output level is designed to be 50% of the logic 0 level. The power supply range is 3.3V to 7.0V and the current consumption is approximately 85 mA.

In conclusion, the SG-8003CG-PEL is a programmable oscillator developed by SEI Company for high precision timing applications. It is based on a triple-modulus prescaler and a phase comparator and can be used in a wide range of temperature and voltage variations. It provides temperature compensation and power supply rejection and is suitable for applications such as telecommunications, automotive, medical, and other precision timing applications. It also features an adjustable output frequency and a low power consumption.
