This specification describes a serialized interface between data converters and logic devices. It contains normative information to enable designers to implement devices that communicate with other devices covered by this specification. Informative annexes are included to clarify and exemplify the specification.
Due to the range of applications involved, the intention of the document is to completely specify only the serial data interface and the link protocol. Certain signals common to both the interface and the function of the device, such as device clocks and control interfaces, have application-dependent requirements. Devices may also have application-dependent modes, such as a low power / shutdown mode that will affect the interface. In these instances, the specification merely constrains other device properties as they relate to the interface, and leaves the specific implementation up to the designer.
Revision A of the standard was expanded to support serial data interfaces consisting of single or multiple lanes per converter device. In addition, converter functionality (ADC or DAC) can be distributed over multiple devices:
