Serial ADC-DAC Implementation in FPGA

ADC-DAC Implementation in FPGA:

Source: Cosmic circuits

• To test the ADC-DAC read-write logic in FPGA, the above algorithm will be implemented in FPGA.
• Serial ADC-DAC is considered for the test. 
• Analog voltage sensed by the ADC is converted in to digital. The digital pattern is written to DAC through FPGA. 
• DAC - Analog voltage output should be same what ADC sensed @ the input.

ADC Read Operation:

• When CS selects goes low, the FPGA will start reading the serial data send by the ADC.

DAC Write Operation:

• When Sync signal goes low, FPGA write the digital data to the DAC. 

Waveforms:

ADC-CS and Serial Data

ADC-Serial Data and Serial Clock

DAC - Sync and Serial Data
