SIT9005ACU1H-30NA

Programmable oscillators are widely used in various fields and have become one of the most important components for many electronic products. Today, we will introduce a type of programmable oscillator -SIT9005ACU1H-30NA and its application field and working principle.

SIT9005ACU1H-30NA is a programmable oscillator developed and produced by SiTek. It uses quartz chip as frequency reference and has low noise, low phase and frequency jitter, and small size. It also has a wide frequency range (1MHz~400MHz) and can realize differential outputs or single-ended outputs, which makes it widely used in communication systems, data networks and many other fields.

The working principle of SIT9005ACU1H-30NA oscillator is mainly realized by oscillation circuit and frequency synthesis circuit. The frequency synthesis circuit uses a Phase-Locked Loop (PLL) circuit to synthesize the exact oscillation frequency that is digitally generated by the oscillator. The oscillatory circuit will convert the frequency signal from the frequency synthesis circuit into a finite voltage signal which can drive the quartz oscillator, so that a regular and stable clock signal can be output. Moreover, the oscillation frequency can be programmed by changing the PLL centre frequency, which makes its application more flexible.

The application field of SIT9005ACU1H-30NA oscillator mainly includes telecommunication systems, such as GSM/CDMA, WiMAX, etc., data networks, such as Ethernet, Bluetooth, Wi-Fi and other television broadcast systems, as well as other industrial scientific instruments. For example, it can be used in FPGA chips or communication control circuits of an electronic product, to ensure the accurate timing and synchronization of the electronic product.

In conclusion, SIT9005ACU1H-30NA oscillator is a very popular programmable oscillator with a wide application range and a stable performance, which can be used in many electronic products.
