Analog-to-digital (AD) converters are one of the most important components in many applications, especially in the fields of medical imaging, automotive industry, aerospace, telecommunications, military and more. They are used to convert continuous analog signals into discrete, discrete-time signals. The DC1563A-G is a low-power, very wide-dynamic range, 40-bit, highly integrated device designed for rapid prototyping and the development of evaluation boards and data acquisition systems. In this article, we\'ll discuss the application field and working principle of the DC1563A-G.

Application field of the DC1563A-G

The DC1563A-G is a low power, 40-bit, highly integrated AD converter with wide dynamic range. It is suitable for applications such as medical imaging, automotive industry, aerospace, telecommunications, military and more. The on-board ADC and FPGA provide high accuracy data acquisition with low power consumption. The ADC features include 16-bit resolution, dual-channel simultaneous conversion, auto-zero track/hold, fast acquisition speed, 10-bit analog input range, 12-bit digital output range, onboard clock, and small-signal bandwidth up to 100MHz. The FPGA provides high-fidelity signal routing to on-board peripherals, allowing for multi-channel DAC operation and other features. The board also features on-board prototyping tools such as LEDs, potentiometers, resistors, capacitors, switches, and SPDT relays.

Working principle of the DC1563A-G

The DC1563A-G operates on a single 32 GHz reference clock. This reference clock is used to synchronize an analog-to-digital conversion sequence between the ADC and FPGA. When an input signal is developed, the FPGA provides timing signals based on the reference clock to the ADC. The FPGA then digitize the analog signal according to the ADC\'s sampling clock. The digitized signal is then processed in the FPGA, including data processing, filtering, and other related tasks. The output from the FPGA is then routed to on-board peripherals and can be used for further data acquisition, or can be further processed into digital output signals.

The DC1563A-G supports two calibration modes: open-loop and closed-loop calibration. In open-loop calibration, the FPGA adjusts the ADC’s reference voltage level by gain and offset adjustments using stored values. Additionally, manual offset and gain controls can be used for fine adjustments. In closed-loop calibration, the FPGA dynamically adjusts the ADC’s reference voltage level by performing a series of measurements to determine optimal voltage levels for each analog input. This allows for higher accuracy conversion and dynamic range.

The DC1563A-G also supports configurable I/O capabilities. The on-board FPGA can be used to program multiple I/O functions such as digital inputs/outputs, analog inputs/outputs, and digital/analog mixed signal conversion. This gives users a high degree of flexibility for customizing their applications. The board also supports analog signal conditioning, which can be used for applications such as high-speed feedback control and data acquisition.

Overall, the DC1563A-G is an ideal solution for rapid prototyping and ad evaluation boards. Its wide dynamic range, low power, and configurable I/O capabilities allow for rapid development and testing of a variety of applications. Additionally, its calibration modes provide higher accuracy conversion and dynamic range. With its wide array of features, the DC1563A-G is suitable for many application fields including medical imaging, automotive industry, aerospace, telecommunications, military, and more.
