Optimize data transmission on FPGAs!
What is JESD204?
The JESD204 standard is a serial interface developed to simplify and accelerate communication between data converters (e.g. ADCs and DACs) and digital components (e.g. FPGAs). Used in fields such as aerospace, defense and telecommunications, the JESD204 standard enables fast, reliable data transfers while reducing wiring complexity, which is crucial for embedded systems and devices requiring low latency and high efficiency.
The JESD204 standard is available in several versions, such as JESD204B and JESD204C, which bring successive improvements in speed and performance.
JESD204 operating principles
Unlike older parallel interfaces, JESD204 uses serial transmission lines, reducing the number of connections and simplifying wiring. More recent versions increase bandwidth capacity and introduce advanced synchronization features to ensure stable, accurate transmission, essential in applications where latency and reliability are critical.
JESD204 applications
The JESD204 standard is used in applications where transfer speed and accuracy are crucial to overall system performance:
- Aerospace and defense: for fast, reliable data transmission between sensors and processors
- Communication systems: where low latency is essential for real-time processing
- Test and measurement equipment: requiring a high-precision interface for complex data analysis
- Medical imaging: enabling fast, accurate data transmission from sensors to processing units
Each JESD version has been developed to meet the growing need for high-speed transmission. For example, version JESD204B introduced improved synchronization management. JESD204C offers even higher data rates, essential for applications requiring low latency and high efficiency in modern embedded systems.
