Programmable oscillators, known as POs, are controllable over a range of frequencies and offer applications in fields such as frequency synthesis and timing control. The SIT9005ACF1H-33EF is a type of planar micromechanical (PM) PO from Symmetry Electronics that is capable of precise and ultra-high frequency operation. This article will explain the application field and working principle of the SIT9005ACF1H-33EF.The SIT9005ACF1H-33EF is suitable for use in applications such as body-worn sensors, industrial and automotive instrumentation and test equipment. The ripple of the SIT9005ACF1H-33EF is typically at 0.5Ps shift over a broad frequency range, ensuring precise and reliable frequency control with minimal additional components. It has an output power of 0 dBm, with a frequency range of 10MHz to 67MHz, and a temperature stability of ±0.3 ppm/°C.The SIT9005ACF1H-33EF utilizes a planar micromechanical (PM) configuration, which consists of an oscillator core of interdigitated comb fingers. The PM configuration delivers significant improvements in frequency accuracy, pairing the small size and low-power of a MEMS oscillator with the reliable long-term stability and accuracy of a quartz crystal oscillator. The SIT9005ACF1H-33EF has a maximum frequency drift of 1.5 ppm/°C, allowing it to maintain accurate operation even under extreme temperatures.The SIT9005ACF1H-33EF has two different operation modes: fixed frequency and programmable frequency. In fixed frequency mode, the SIT9005ACF1H-33EF is set to a single output frequency, with no programming required, while in programmable frequency mode, the frequency range can be tuned to a user-defined value. The SIT9005ACF1H-33EF utilizes a digital interface that allows the user to read and write a variety of settings, including frequency, temperature, power, frequency offset and acceleration compensation.The SIT9005ACF1H-33EF also features an automatic temperature compensation (ATC) function, which adapts the output frequency to changes in temperature. The ATC feature ensures that the SIT9005ACF1H-33EF can maintain its frequency stability, even in harsh environments. The SIT9005ACF1H-33EF is also equipped with an integrated phase-locked loop (PLL) for precise frequency control. In summary, the SIT9005ACF1H-33EF is a programmable oscillator capable of precise and ultra-high frequency operation. It is suitable for applications such as body-worn sensors, industrial and automotive instrumentation and test equipment, offering improved frequency accuracy and a maximum frequency drift of 1.5 ppm/°C. It features a digital interface, allowing the user to read and write a variety of settings, and also features an automatic temperature compensation function and an integrated phase-locked loop for precise frequency control.
