Teledyne e2v EV10AS940: Revolutionizing Microwave ADCs

EV10AS940In today's rapidly developing technology, high-speed data acquisition and processing capabilities are key to driving innovation. Teledyne e2v's latest masterpiece, the EV10AS940, is an advanced microwave analog-to-digital converter (ADC) that can meet the needs of high-speed data acquisition. This 10-bit single-channel, 12.8 GSPS ADC not only stands out for its excellent performance, but also sets a new benchmark for the industry with its integrated digital functions - frequency hopping and beamforming.

Frequency hopping function: flexible data acquisition

The frequency hopping function of EV10AS940 allows users to select specific frequency bands from the collected data for optimization, thereby effectively reducing the amount of data transmitted to the FPGA. This function is achieved through digital down-conversion. Users can activate up to 4 digital channels and configure frequency and phase parameters independently for each channel. In the actual demonstration, the combination of Teledyne AS940 FMC+ evaluation board and FPGA motherboard shows how to configure parameters and adjust them in real time through a graphical user interface (GUI).

The experimental platform includes multiple signal generators and adders, which provide a rich set of test signals for the ADC. Through the GUI, users can easily set the frequency and phase to achieve precise control of the ADC. In addition, through the fast frequency hopping (FFH) function, users can use GPIO to select different parameter sets to achieve fast frequency switching, which is particularly important in application scenarios that require fast response.

Beamforming: Precise signal positioning

In addition to the frequency hopping function, the EV10AS940 also supports beamforming, which is a function that can independently set the gain and delay of each DDC channel. By precisely controlling the timing of the signal, beamforming technology can significantly improve the positioning accuracy of the signal. In the demonstration, by activating 4 channels and setting the corresponding NCO frequency, the user can intuitively view the delay effect on the IQ diagram.

The use of the beamforming tab further simplifies the process of setting gain and delay. Users can adjust the gain of each channel through an intuitive interface, as well as select integer delay or fractional delay for finer signal control. This flexibility is particularly critical in multi-chip synchronization and digital beamforming applications, which can significantly improve the overall performance of the system.
