Oscillators: PDF620003 Application Field and Working Principle

Oscillators are electronic circuits that generate a periodic, oscillating signal without an input. Oscillators are frequently used for communications purposes, such as cell phones, radios, and satellites. Oscillators can be used for frequency timing, frequency division, and as a clock signal in digital circuits. PDF620003 is one of the most commonly used oscillators in the electronic industry. This article will discuss its application field and working principle.PDF620003 is a dual frequency, medium frequency, surface mount oscillator, designed for applications requiring a wide output frequency range and low power consumption. It is manufactured by Pulse Electronics Corporation and is available in a standard 6-pin ceramic package. It provides a wide selection of output frequency ranges from 10 MHz to 66.667MHz. It is designed for applications including frequency generation for video game systems, paging systems, cellular multi-users, and digital signal processing (DSP) applications.The PDF620003 has a maximum output of +3dBm and is available in a closed loop or open loop configuration. In a closed loop configuration, the oscillator is designed to maintain frequency stability and is capable of maintaining a very low phase noise level. In an open loop configuration, the oscillator stability is reduced and the output phase noise level is increased. The oscillator is also equipped with automatic gain compensation for improved frequency stability.The PDF620003 is powered by an internal 5V DC supply, with a maximum current consumption of 40mA at 3.3V. It is designed to operate over an operating temperature range of -40C to +85C and has a maximum shock resistance of up to 1000G. The oscillator is stable even when subjected to environmental and mechanical shock, long term stability, and vibration.The PDF620003 is capable of generating low jitter clock signals. It has an integrated phase-locked loop (PLL) that simplifies the design and provides high precision tuning. It is capable of providing five output frequencies at the same time, allowing for simultaneous output frequencies over a wide range. It also features high-frequency operation and a wide supply voltage range of 2.7V – 3.3V.The PDF620003 working principle revolves around the use of an internal PLL to generate a stable output signal. The PLL is composed of a Voltage Controlled Oscillator (VCO) and a phase frequency detector. The PLL is programmed to maintain a specific phase and frequency relationship by controlling the VCO frequency. When the input frequency changes, the phase detector senses the change and adjusts the frequency of the VCO to maintain the desired frequency and phase relationship.The PDF620003 is a versatile oscillator suitable for a wide range of applications. Its wide output frequency range and low power consumption make it an ideal choice for video game systems, pager systems, cellular multi-users, and digital signal processing (DSP) applications. Its advanced features and high frequency operation combined with a wide supply voltage range of 2.7V – 3.3V make it an excellent choice for reliable and accurate frequency generation.
