Programmable oscillators are electronic components which are widely used in all kinds of electronic systems. Their purpose is to generate a specific and controllable frequency for oscillatory circuits, so that system performance can be optimized for specific tasks. One of these programmable oscillators is SIT9005ACB1H-XXDP, which is a very common and widely used programmable oscillator in the market. In this article, we will discuss the programmable oscillators of SIT9005ACB1H-XXDP, its application fields and working principle.

SIT9005ACB1H-XXDP programmable oscillator is available in two models: the standard model which is an analog oscillator and the PWM model which is a digital oscillator. It is a high performance oscillator with a wide frequency range from 1 kHz up to 250 MHz. It also has an adjustable power supply from 1.8V to 3.3V and a wide range of temperature compensation from -20°C to +85°C. It is sold in 24-pin dual-in-line packages and has a gold-plated surface mount and reflow soldering compatibility.

The main application of SIT9005ACB1H-XXDP programmable oscillator is as a replacement of crystal oscillators in many embedded products, such as cell phones, medical equipment and HDTV. In these products, it is used to provide stable and precise clock signal at frequencies ranging from 1 kHz to 250 MHz. Its stability is much better than that of crystal oscillators. Furthermore, its adjustable power supply makes it suitable for several different kinds of applications.

The working principle of SIT9005ACB1H-XXDP is similar to that of regular crystal oscillators. It depends upon the properties of an LC (inductance-capacitance) filters and varistors to limit the range of frequencies that are generated. The frequency is then determined by the Configuration DAC (Digital-to-Analog Converter) which is connected to the oscillator. It also has a fast frequency lock time of 1 µs and it supports phase-locking for even faster frequency sweep.

In summary, SIT9005ACB1H-XXDP is a very common and widely used programmable oscillator due to its adjustable power supply and wide temperature compensation range. It is used in many embedded products as a replacement of crystal oscillators and it works on the same principle as a regular crystal oscillator, with the advantage of a faster frequency lock time and phase-locking support. Thus, it is an ideal choice for low-power circuits requiring accurate and stable frequency generation.
