Programmable oscillators are control devices responsible for creating and maintaining a timing signal at a frequency controlled by a microcontroller or a system of dedicated circuitry. SIT9005ACF1H-XXEB Programmable oscillators are widely used in the communication, medical, industrial and consumer industries. This article discusses the application field and working principle of SIT9005ACF1H-XXEB programmable oscillators.

Application field of SIT9005ACF1H-XXEB Programmable Oscillators

SIT9005ACF1H-XXEB Programmable Oscillators are Programmable Oscillators (PPMs) that have been designed for use in specific applications. The flexible nature of the PPM makes them suitable for a wide range of applications, as they can be programmed to produce a wide range of frequencies. They are ideal for applications where rapid frequency adjustment is required, such as communications, control, and industrial systems.

They can be applied in graphics processing display, radio frequency identification (RFID), and television devices, as well as in computers, base stations, point-of-sale systems, and car audio systems. Programmable oscillators are also frequently used in medical electronics, automotive electronics, and environmental monitoring. Additionally, SIT9005ACF1H-XXEB Programmable Oscillators support slewing of the output frequency for communications in order to reduce EMT emission.

Working Principle of SIT9005ACF1H-XXEB Programmable Oscillators

SIT9005ACF1H-XXEB Programmable Oscillators utilize a phase-locked loop (PLL) technique to generate output frequencies that span the range from 400kHz to 700MHz. The oscillator consists of a precision frequency reference source (which can be either an external or an on-chip crystal) and a voltage-controlled oscillator (VCO). The frequency reference and the VCO are compared by a phase detector/filter in order to set the PLL loop gains so that the output frequency, or comparison frequency, is locked to a multiple of the reference frequency.

The reference frequency is divided down to a programming frequency by a programmable frequency divider, which enables the user to select the frequency of the output signal. The VCO and the reference are compared by a phase detector, which then feeds the error signal to the loop filter. The loop filter creates a control voltage that is then used to adjust the VCO frequency until it is in phase-lock with the reference frequency.

SIT9005ACF1H-XXEB also offer advanced features such as built-in memory for easy storage and recall of settings and programmability of cable delay and attenuation. Additionally, they feature a wide operating temperature range and are designed to reduce EMI emissions. SIT9005ACF1H-XXEB Series oscillators are designed to meet stringent jitter and frequency stability specifications, making them ideal for mission-critical applications.
