Programmable oscillators, such as the SIT9005ACE1D-25EN, are specialized electronic circuits designed to generate specific frequencies. They are used in a variety of applications, from communication systems to microcontroller control. In this article, we will explore the application field and working principle of the SIT9005ACE1D-25EN.

The SIT9005ACE1D-25EN is a microprocessor-controlled, programmable crystal oscillator (MCXO) that offers frequency stability to ±25ppm over the industrial temperature range of -40°C to +85°C. It has a high range of supply voltages from 2.7V to 3.3V and is pin-compatible with standard oscillators. The SIT9005ACE1D-25EN is especially suitable for a wide range of applications, including GPS receivers, navigational systems, avionics, satellite communications, cellular base stations, Wi-Fi routers, surveillance cameras, enterprise switches, industrial automation, and medical applications.

The MCXO technology in the SIT9005ACE1D-25EN enables frequency stability over temperature to be maintained without the need for external temperature compensation. In standard oscillators, thermal changes in the environment affect oscillator frequency, which must then be compensated by either mechanical or electronic components. The SIT9005ACE1D-25EN eliminates the need for such external components and provides better stability over temperature changes. So, it is especially suitable for applications where speed and temperature have a direct effect on device performance.

The SIT9005ACE1D-25EN uses an oscillator core that consists of two fundamental components, a quartz crystal and an integrated circuit (IC). The quartz crystal is a mechanical resonator that vibrates at its resonant frequency when an alternating current is applied across its two electrodes. The alternating voltage and current at the crystal interface of the IC form an oscillator circuit that resonates at a frequency determined by the crystal. This oscillator causes a continuous frequency output from the oscillator package as long as a power supply is applied to the oscillator.

The SIT9005ACE1D-25EN includes an on-board temperature sensor that compensates for ambient temperature changes to ensure stable oscillator output. It uses the information from the temperature sensor to determine whether further compensation is necessary, and adjusts the resonant frequency of the oscillator accordingly. This process allows the oscillator to maintain stability over negative and positive temperature changes.

The SIT9005ACE1D-25EN is an ideal choice for applications where frequency precision and stability is required. It is also highly configurable and programmable, enabling flexible frequency settings. This makes it suitable for a wide variety of applications that require precise control over frequency and temperature.The SIT9005ACE1D-25EN is an ideal choice for applications where frequency precision and stability is required.
