Programmable oscillators are devices that enable users to configure or create clock signals, of different frequencies and performance characteristics, for various applications. One of the popular programmable oscillators on the market is the SIT9005ACR2G-25EF. This article will discuss the working principle and application field for this oscillator.

Working Principle

SIT9005ACR2G-25EF is a programmable zero-delay buffer oscillator that uses an advanced programmable SIT™ high speed ASIC (Application-Specific Integrated Circuit) to deliver highly precise clocking. It features advanced features such as zero-delay buffer and wide operating temperature range (-40 to 85 °C). It has a maximum frequency of 25 MHz and a voltage input range of 4.5-5.5 volts. Its extremely low jitter and high frequency modulation capabilities make this oscillator an ideal choice for many types of applications.

At the heart of the SIT9005ACR2G-25EF oscillator is a charge-pump phase-locked loop (PLL) with multiple stages. The loop consists of two main components: the voltage-controlled oscillator (VCO) and the phase-frequency detector (PFD). The VCO is responsible for generating the clock signal while the PFD is responsible for detecting any difference between the reference generator and the VCO and providing corrective action to the loop.

The VCO is powered by an external voltage source and its output is fed through the PLL loop. The frequency of the created signal is determined by the amount of charge injected into the loop by the charge-pump. The amount of charge is controlled by the voltage on the external voltage source. This is how the SIT9005ACR2G-25EF oscillator is programmed and makes it a truly programmable oscillator.

Application Field

The SIT9005ACR2G-25EF oscillator is ideal for many applications, from consumer electronics to industrial and medical applications. Its low jitter and high frequency modulation capabilities make it an excellent choice for projects that require high accuracy.
