Eclypse Z7 Low Level Zmod ADC DAC Demo

Overview

The project demonstrates the implementation of a basic signal processing

application on the Eclypse platform (Eclypse Z7 + Zmod ADC + Zmod DAC).

Description

The simplified block diagram of the system implemented for this demo is shown

below:

An analog input coming from the Analog Discovery 2 (AD2) is connected to the

Zmod ADC 1410 CH1, converted to a digital format and passed on to the input of a

digital low pass filter. The filter's output is converted back to an analog format by the

Zmod DAC 1411 and can be measured/visualized on the converter channel 1.

The input signal, after the analog to digital conversion, is also looped back to the Zmod DAC 1411 and connected to CH2 output. The Analog Discovery 2's Network Analyzer instrument is then used to plot the frequency characteristic using the CH2 of the Zmod DAC 1411 as reference. The purpose of the digital loopback is to correct the phase errors introduced by the ADC and Zmod ADC 1410 Low Level Controller latency and the gain errors caused by the mismatch between the ADC and the DAC full scale voltages.

Demo Setup Hardware Setup 1. Connect the Analog Discovery 2 board to the host computer using a MicroUSB cable. 2. Connect the Eclypse Z7 board to the host computer using a MicroUSB cable through PROG MicroUSB port and power the board using the 12V Power Supply. Flip its power switch to turn it on. 3. Connect the two Zmods ADC and DAC to the Zmod connectors of the Eclypse Z7 board as follows:   Zmod ADC 1410 to ZMOD A connector of the board Zmod DAC 1411 to ZMOD B connector of the board 4.
