It has been specifically developed for frequency control in next-generation cellular and multimedia applications. In terms of function, it integrates a programmable divider and VCO, and can be programmed with a default frequency range of 4GHz to 4.8GHz.

Application and Working Principle

The SIT9120AC-2C3-25E75.000000Y is suitable for consumer electronic equipment and 802.11a, 802.11b, 802.11n, and 802.11ac applications. It supports typical ultra-low-power applications such as satellite navigation systems, industrial automation and control, or instrumentation control systems. Moreover, the device can be used with a programmable divider and VCO. The device can be programmed to use a range between 4GHz and 4.8GHz.

In terms of working principle, the SIT9120AC-2C3-25E75.000000Y can reach up to 4.8GHz operation frequency. It uses a reference clock input, a VCO control voltage and an enable/disable function to control the output frequency. The reference clock input is typically a 50Mhz signal, which is divided down to achieve the 4.8GHz frequency. The VCO control voltage is used to control the frequency output and the enable/disable function is used to control the output on/off status.

The oscillator is also known for its low power consumption and is usually specified for transceiver applications. The device consumes as low as 10mA and 6mA over a wide operating voltage range. The output frequency is determined by the input reference frequency, the voltage of the control voltage, and the setting of the frequency divider. The output frequency can be divided up to the seventh harmonic and the frequency is factory trimmed for improved accuracy.
