Programmable Oscillators

The SIT9005ACL2H-18SA is one of the programmable oscillators of the Sitronix family of frequency controllers. It is a three-channel frequency controller with an adjustable frequency range of 16 kHz to 1 MHz. It is an excellent choice for applications that require a high degree of accuracy and stability over a wide range of frequencies. It is also an ideal choice for applications that require the ability to adjust the frequency of the oscillator without power cycling.

It is a Low Noise Oscillator that has a CMOS interface and comes with a built-in clock generator. This makes it perfect for applications that need to adjust the frequency of oscillators with minimal disruption or noise. The SIT9005ACL2H-18SA has two frequency outputs and one adjustable output that is used to control the alternative oscillator’s frequency.

Application Field

The SIT9005ACL2H-18SA is designed for use in mobile applications including cellular phones and PDAs as well as for industrial instrumentation and/or machine control. It is also suitable for use in automotive, video and telecommunication equipment, computer peripherals, and multimedia products. It can be used in a wide range of applications where accurate frequency and pulse control is needed.

Working Principle

The SIT9005ACL2H-18SA frequency controller consists of a control module, an oscillator, and a thermal management device. The control module includes a Programmable Control Unit (PCU) that is used to adjust the frequency of the oscillator. The oscillator is made using a high precision silicon resonator and is capable of holding its frequency over a wide temperature range. The thermal management device helps to maximize the life of the oscillator by keeping it at optimal operating temperature.

The Programmable Control Unit (PCU) is composed of two separate parts, one for adjusting the frequency and the other for adjusting the duty cycle. The frequency is adjusted by programming the frequency setting and the duty cycle is adjusted by programming the counter configuration. The PCU also features numerous features such as programming mode for further fine tuning.

To ensure the highest stability and accuracy of the SIT9005ACL2H-18SA, a precision frequency reference clock is used to provide an accurate time reference and a phase-locked loop technique is used to adjust the frequency of the oscillator. The phase-locked loop technique requires the oscillator to be locked to an external reference clock, thereby ensuring the accuracy and stability of the oscillator.

The SIT9005ACL2H-18SA has a wide range of applications and is suitable for use in a variety of industrial, automotive and communication systems. Its ability to accurately adjust frequencies without power cycling and its low power requirements makes it an ideal choice for many applications.
