Programmable oscillators such as SIT9005ACA1G-28NJ can be used for a range of purposes, from generating precise frequencies for wireless communications to providing a basis for real-time clocks. They are designed for use in control, timing and communications applications, allowing users to customize their settings and parameters to suit their particular needs. This article explores the application field and working principle of SIT9005ACA1G-28NJ.

The SIT9005ACA1G-28NJ is a programmable oscillator, typically used in applications where precise timing is important. It is a high-accuracy clock oscillator, offering excellent reliability and low power consumption. It is based on a technology called direct digital synthesis, which allows the user to program the oscillator frequency, providing accuracy within 0.01ppm (parts per million). This makes it ideal for use in applications such as telecommunications, RFID (radio-frequency identification) and test equipment, where precise clock frequency generation is required.

The clock oscillator combines a high-accuracy voltage-controlled crystal oscillator (VCXO) with a low-jitter voltage controlled signal generator based on direct digital synthesis (DDS). The VCXO allows for a range of frequencies between 19.44MHz and 80.00MHz, providing a range of operating frequency accuracy from 0.02ppm to 0.2ppm. The signal generator uses the Direct Digital Synthesis (DDS) method, which uses digital code to generate an accurate frequency. This digital code allows the device to generate an accurate signal over a wide range of frequencies. The signal generated by the SIT9005ACA1G-28NJ can be further adapted and calibrated by programming the built-in EEPROM. This programming can be used to adjust the center frequency, resolution and accuracy of the signal.

The frequency output of the SIT9005ACA1G-28NJ is programmable between 19.44MHz and 80.00MHz and is calibrated to within 0.02ppm and 0.2ppm accuracy. The device can also be programmed to generate frequencies from 0Hz up to 50MHz in the Pulse-Width Modulation (PWM) mode. The PWM mode operates by modulating the output signal using a built-in pulse-width controller. The signal generator has an output impedance of 110Ohms and a maximum output voltage swing of up to 2.5V. It is designed to be used in conjunction with an external load and signal input.

The SIT9005ACA1G-28NJ is designed to provide an extremely accurate frequency with low jitter and excellent reliability. It can be used in a range of different applications including test equipment, wireless communications and RFID systems. The programmability of the SIT9005ACA1G-28NJ makes it ideal for applications where precise timing is essential, allowing users to adjust the center frequency, resolution and accuracy of the signal produced. This makes it an ideal choice for use in applications requiring an accurate and precise frequency.
