Programmable oscillators like the SIT8008ACE3-25E are widely used in a range of applications. From regulating timing circuits to providing an accurate time reference for data transmission, these oscillators have become a major component in many electronic systems. The SIT8008ACE3-25E is a surface mounted PLL voltage-controlled oscillator that combines a high-speed PLL, low-jitter oscillator, and high-precision 90° phase/frequency detector (PFD). This unique combination gives the SIT8008ACE3-25E superior stability and performance while consuming less power than traditional oscillators.

Working Principle

The SIT8008ACE3-25E works by using feedback to compare the output frequency to the reference frequency. This feedback signal is then used to adjust the internal circuits. The oscillator is composed of a phase/frequency detector (PFD) integrated circuit, a voltage-controlled oscillator (VCO), and a loop filter. The PFD is responsible for comparing the input reference frequency with the actual output of the oscillator. It then sends a voltage proportional to the difference between the two frequencies to the VCO. The VCO then adjusts the output frequency of the oscillator according to the signal from the PFD.

The loop filter is responsible for providing a low-bandwidth filter that removes noise from the circuit and prevents instability. By controlling the gain of the PFD and VCO, the filter reduces the time it takes for the adjustment loop to respond to changes in the input reference. The filter also reduces the amount of power used by the oscillator while keeping the oscillator frequency stable.

Application Field

The SIT8008ACE3-25E is an ideal solution for high-speed PLL applications, as it offers superior jitter performance and a fast lock time. When paired with a high-speed clock generator and digital PLL, it is suitable for applications where low-jitter and low-noise oscillators are needed. It is also used in applications such as driving synchronized communication networks, regulating switching power supplies, and synchronization and regeneration of high-speed signals.

The oscillator can also be used in radio frequency (RF) systems. It is capable of providing high frequencies for baseband and transmission control protocol over Ethernet (TCP/IP) systems. It is also suitable for applications requiring precision control at high frequencies, such as mobile radio systems and Wi-Fi. Other applications include spread spectrum ca transmissions, and packet voice systems.

The SIT8008ACE3-25E is a reliable, power-efficient oscillator capable of providing superior jitter performance and fast lock times, making it suitable for a wide range of applications. Its surface mounted technology and high speed PLL make it an ideal solution for many systems that require precise frequency control.
