In the realm of digital communication, the need for high-speed data transfer has become increasingly critical. Whether it's in telecommunications, industrial automation, or aerospace applications, efficient and reliable data transmission is essential for driving innovation and progress. One technology that has significantly contributed to this domain is JESD204B.

JESD204B, short for JEDEC Standard 204B, is a widely adopted serial interface standard developed specifically for high-speed data converters. It provides a robust framework for transferring data between analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) and the associated digital signal processing components

This standard offers several advantages over its predecessors, including higher data rates, improved synchronisation capabilities, and reduced system complexity. By utilising high-speed serial lanes, JESD204B enables data rates of up to several gigabits per second, enabling the efficient transmission of large amounts of data in real-time. JESD204B also simplifies system design by reducing the number of physical interconnects and eliminating the need for complex analog front-end circuits. This streamlining not only enhances system reliability but also reduces overall costs, making it an attractive choice for various industries.

JESD204B incorporates a powerful synchronization mechanism that allows for precise alignment and synchronisation of multiple data converters within a system. This capability is particularly valuable in applications that require multiple channels working in concert, such as phased-array radar systems or high-density data acquisition systems.

In conclusion, JESD204B has revolutionised high-speed data transfer in digital communication. Its ability to support faster data rates, improved synchronisation, and simplified system design has made it a preferred interface standard for a wide range of applications.

As technology continues to advance, JESD204B will undoubtedly play a crucial role in driving further innovation and enabling the next generation of high-performance digital communication systems.

JESD204B demonstration developed by reflex ces for high speed data conversion

The reflex ces team has developed a demonstration based on the JESD204B standard, available for the Achilles Arria® 10 SoC module. A reference design is also available.


Since it's inception back in 2016, the popular Achilles Arria® 10 SoC System-on-Module (SoM) has supported a wide range of customers and applications. It has been recently updated to support new features and higher speed interfaces.

The updated Achilles SoM features 4GB DDR4 and 32eMMC NAND while adding an I²C serial flash device to store nonvolatile user data which provides a simple method to uniquely identify each SoM. It also provides support for increased transceiver interface data rates up to 12Gbps for video standards such as 12G-SDI, or High-Speed Data conversion using JESD204B.

For simplified development and enhanced time to market a Development Kit with the Starter Carrier board, or with a PCIe carrier board is available separately. The Achilles SoM can be purchased separately for production systems in three different versions: Lite 12G, Indus and Indus 12G.
