Analog to Digital Converters (ADCs) are important components of many electronic devices. As the name indicates, they are used to convert analog signals into digital signals in order to be processed further. Many of these ADCs come in the form of evaluation boards. One such board is the ADS52J90EVM. This article looks at the application field and working principle of this particular EVM.

Application Field

The ADS52J90EVM is an evaluation board primarily designed for the evaluation of the ADS52J90 dual channel LVDS A/D converter. This board has been specifically designed to help with the testing and development of system-level applications such as medical, imaging, audio, and radar systems. The important features of the board make it suitable for a range of tasks, from design validation to board characterization.

The key advantages of the EVM are:

• High sampling speed with sample rate up to 400Msps
• Dual 12-bit channels provides a reliable A/D conversion process
• 2MHz bandwidth amplifier provides good linearity and accuracy
• On-board 1GHz sine and square wave generator provide reliable reference signal and test signals for the evaluation
• On-board signal source with 12-bits accuracy enables precise and accurate tests
• Small form factor and easy to integrate into any system

The ADS52J90EVM is suitable for a wide array of applications such as imaging, medical and audio. It is also well suited for testing and development of radar systems due to its high sampling speed. This makes it an ideal choice for designers looking for a reliable, fast, and accurate board for their analysis and testing needs.

Working Principle

At a high level, the ADS52J90EVM converts analog signals into digital signals using its dual channels. Each channel consists of a 12-bit conversion register which is capable of producing digital data at a rate of up to 400Msps, or megasamples per second. These two channels are combined with a clock source to provide accurate, synchronous digital data.

The conversion of analog signals to digital signals is done via the dual channels. The two channels use LVDS (low voltage differential signaling) to accurately and quickly convert analog signals into digital signals. LVDS is an advanced technology that allows for speedier data transmission while providing good reliability.

The on-board signal source is used to provide an accurate and reliable reference signal for the tests. This is an adjustable 1GHz sine and square wave generator, which can be used to produce the required signals. The signal source helps to ensure that the test results are accurate and reliable.

Furthermore, the ADS52J90EVM includes an on-board wideband amplifier to provide additional linearity and accuracy. This amplifier provides a 2MHz bandwidth which allows for the devices connected to the board to be analyzed quickly and accurately.

In summary, the ADS52J90EVM is an evaluation board designed for the testing and development of systems which use dual channel LVDS A/D converters. It features a 12-bit conversion rate, a signal source with 12-bit accuracy, and a wideband amplifier. The EVM is suitable for system-level applications such as imaging, medical and audio. It is also well-suited for testing and development of radar systems due to its high sampling speed and reliable accuracy.
