Asynchronous multi-channel ADC and DSP processor interface

System-on-chip technology requires smooth interfacing between its various peripherals and processors. Multi-channel Analog-to-Digital Converter with high speed and serial interface even raises more challenges to the designer in order to interface the ADC with processor. In this paper, we present the interface design between a multi-channel ADC and high speed DSP processor for system-on-chip design. The Analog Devices´ AD9219 is selected because it is designed for low cost, low power consumption, small area size and ease of use. We have implemented the VSLI design of the interface to pass data from ADC to DSP processor. The interface uses asynchronous FIFOs with Gray code synchronization technique to handle synchronization issue created from two clock domains. We have explained the application of the design to show the connectivity between the ADC, the ADC interface and the DSP processor.
