JESD204 is a standardized serial interface used by data converters (ADCs and DACs) and logic devices (FPGAs or ASICs). This interface was developed by the JEDEC JESD204 standards committee to reduce the number of data inputs/outputs between high-speed data converters (ADCs and DACs) and logic devices (FPGAs or ASICs). Other advantages of this interface include a reduced PCB/package area and a simplified interface timing.

There are 3 versions of JESD204:

JESD204 - Developed in 2006.

JESD204A - Released in 2008.

JESD204B - Released in 2011.
