Programmable oscillators are electronic pieces of equipment used to generate well-defined frequencies accurately. SIT9005ACU1G-28NH is one such programmable oscillator, typically used in applications such as Frequency Synthesis, Precision Frequency Control, and Pulse-Width Modulation. This oscillator is a miniaturized, low power, temperature-compensated crystal oscillator (TCXO) module with an integrated voltage-controlled oscillator (VCO) and phase frequency detector (PFD) circuit.

This module offers a wide frequency range from 40 MHz to 630 MHz, with a low power consumption up to 1.5mA per channel. It also has a built in phase locked loop (PLL) which allows the adjustment of the frequency output to a desired level. The SIT9005ACU1G-28NH module also has a wide temperature range of -40℃ to +85℃.

The SIT9005ACU1G-28NH is used in applications where precise frequency control is required. The module uses an integrated circuit to control the frequency of the signal output, enabling accurate control over frequency drift. This makes it ideal for precision frequency control applications such as high-resolution digital-to-analog converters or audio signal processing. It is also used in frequency synthesis applications, which require precise frequency control at a wide range of frequencies. The SIT9005ACU1G-28NH can generate signals up to 630 MHz, making it suitable for such applications.

The working principle of this oscillator is based on the PLL circuit, which is based on the comparison between the desired oscillation frequency and the actual frequency. The voltage control oscillator (VCO) is the actual oscillator that provides the signal output. The PFD circuit is then used to compare the actual oscillation frequency with that desired, and the output of this comparison is used to adjust the frequency of the VCO, thus adjusting the signal output frequency as required.

The SIT9005ACU1G-28NH is a highly reliable, versatile, and accurate programmable oscillator which can be used in a variety of applications. Its wide frequency range and temperature range, low power consumption, and precision frequency control make it suitable for a wide range of applications, such as precision frequency control, frequency synthesis, and pulse width modulation. Its reliable and accurate working principle based on the PLL circuit ensures that the desired output frequency is maintained at all times, making it a great choice for precise and reliable frequency control.
