JESD204B vs. Serial LVDS interface considerations for wideband data converters

The motivation was to standardize an interface that would reduce the number of digital inputs/outputs between data converters and other devices, such as FPGAs (field-programmable gate arrays) and SoCs (systems-on-chip), through the use of a scalable high-speed serial interface.

Trends show that new applications, as well as advances in existing ones, are driving the need for wideband data converters with increasingly higher sampling frequencies and data resolutions. Transmitting data to and from these wideband converters poses a significant design problem as bandwidth limitations of existing I/O technologies force the need for higher pin counts on converter products. Consequently, systems PCB designs have become increasingly more complex in terms of interconnect density. The challenge is routing a large number of high-speed digital signals while managing electrical noise.
