Programmable oscillators offer great versatility in the sense that they can be programmed to operate in any required frequency or output waveform as needed. One such oscillator is the SIT9005ACE1G-30SF. It is a highly integrated device featuring integrated voltage regulators, oscillators, and phase-locked loops (PLLs). Its wide range application fields and the working principle of this component can be explored in the following. Application FieldThe SIT9005ACE1G-30SF can be used in different kinds of application fields. Due to its ultra-low power operation (up to 15μA), this component is suitable for battery operated devices. In addition, it is suitable for mobile communication devices, such as cellular phones, wireless base station equipments, GPRS and EDGE terminals, etc. Additionally, this component can be used for applications in any common digital logic and embedded processor applications, including microcontrollers, DSPs, ASICs, and FPGAs. The main features of the SIT9005ACE1G-30SF include extremely low jitter, low standby current, and wide temperature range operation, making it suitable for applications in many sectors, such as mobile and telecom, automotive, test and measurement, and industrial as well.Working PrincipleThe SIT9005ACE1G-30SF is capable of precise frequency control and generates accurate low jitter output waveform, thanks to its embedded architecture. This oscillator consists of a voltage-controlled voltage regulator (VCVR) and a voltage-controlled oscillator (VCO). The VCVR is used to stabilize the operating conditions and it is capable of operating with extremely low noise. It also ensures a low startup time and is suitable for applications requiring fast start up. The VCO, on the other hand, is used to generate the output waveform. The SIT9005ACE1G-30SF also features a programmable phase-locked loop (PLL) that can be used to frequency synthesize the output waveform. It consists of a reference oscillator, a phase-frequency detector (PFD), a charge pump and a band-pass filter (BPF). The reference oscillator is used to provide a stable reference frequency for the operation of the PLL. The PFD is used to compare the phase difference between the reference and the output signal. The charge pump is then used to amplify the output voltage of the PFD. Finally, the BPF is used to filter out the high-frequency components of the charge pump output. This ensures that the output waveform is clean and precise.The SIT9005ACE1G-30SF also has an integrated programmable EEPROM that stores the control parameters for the oscillator and the PLL. It also has an integrated clock generator that can be used to generate multiple clock outputs with programmable phase delay. This, coupled with its high frequency precision makes it an ideal choice for applications requiring extremely precise timing and phase control.ConclusionThe SIT9005ACE1G-30SF is a highly integrated component designed for use in numerous applications, from mobile communication devices to digital logic and embedded processor applications. Its main features include extremely low jitter, low standby current, and wide temperature range operation, making it suitable for use in a variety of sectors, such as mobile and telecom, automotive, test and measurement, and industrial. It features an embedded architecture consisting of a VCVR, a VCO, and a programmable PLL, and can generate accurate output waveforms with highly precise frequency control. This component is thus ideal for applications that require high precision timing and phase control. Furthermore, its ultra-low power operation (up to 15μA) makes it suitable for battery operated devices. All these features make the SIT9005ACE1G-30SF one of the most versatile programmable oscillators currently available.
