Programmable oscillators are the type of chip-level real-time oscillators that are used to generate precise, reproducible and stable frequency output signals with programmable duty cycles tailored to a specific application. The DSC8104AI2 by DSP7000 is one of such oscillators and is designed for a wide range of application fields.

The versatile design of the DSC8104AI2 allows it to be used in PLL frequency synthesis application, radio broadcast receiver, industrial applications, satellite communication, medical instruments, biometric identification, consumer audio and video, smart building and home automation, automotive infotainment systems and PC peripheral devices to cite a few.

The DSC8104AI2 is a high-precision oscillator with a 20-MHz reference frequency and a 5-kilohertz stepsize, which allows users to tune the system to the desired frequency. In addition, the chip also enables users to adjust the frequency with a resolution of 40kHz and a 10kHz span, creating an environment of excellent frequency stability. Moreover, the adjustable frequency range is up to 120MHz.

In terms of working principles, the DSC8104AI2 is made up of an integrate frequency synthesizer and an oscillator, which are connected in series. The frequency synthesizer uses phase-locked loop (PLL) technology to generate its output frequency, which is then amplified by the oscillator to generate the desired frequency. The frequency synthesizer controls the amplitude of the oscillator’s output signal to ensure resonance, which helps to stabilize the frequency output. The resulting frequency signal is output from the chip using the Serial Peripheral Interface (SPI) or the Remote Direct Memory Access (RDMA).

In conclusion, the DSC8104AI2 is a versatile chip-level oscillator designed for a wide variety of application fields. Its frequency synthesis technology allows the chip to generate highly precise and stable frequency output signals. Additionally, its adjustable frequency range, adjustable resolution and 40kHz span, enables users to fine-tune their system to the desired frequency.
