Connection of Serial ADC to FPGA The ADC (Analog to Digital Converter) can be interfaced to FPGA/ASIC in a different way depending on the output interface. Speech Recognition Software. This post gives an overview on the different interfaces available in ADC interfacing.

DSPI - Serial Peripheral Interface – Master/Slave; DSPI - Serial Peripheral Interface – Master/Slave. VHDL, Verilog: High-Level Model Included?

On modern ADC, when the sampling rate is below the 10 Msample/sec the ADCs often implement a serial interface to provides sampled data to the user. The serial interface is little bit complex w.r.t. A parallel interface but the use of serial protocol reduces the number of wires and allows interfacing the ADC to a microprocessor like Arduino or Rapsberry Pi. In the serial interface, the serial clock provided by the device connected to the ADC is used also as ADC sampling clock. Figure1 – Serial ADC connected to FPGA In this post, we will see an example of how to interface the TI ADC128S022 used in the. Clock Design Overview Often, inside our FPGA design, we have the necessity to generate a local clock from the system clock. With system clock, I mean the clock that is coming from an external board oscillator.
