The Altera JESD204B IP core is a high-speed point-to-point serial interface for digital-to-analog (DAC) or
analog-to-digital (ADC) converters to transfer data to FPGA devices. This unidirectional serial interface
runs at a maximum data rate of 12.5 Gbps. This protocol offers higher bandwidth, low I/O count and
supports scalability in both number of lanes and data rates. The JESD204B IP core addresses multi-device
synchronization by introducing Subclass 1 and Subclass 2 to achieve deterministic latency.
The JESD204B IP core incorporates:
• Media access control (MAC)—data link layer (DLL) block that controls the link states and character
replacement.
• Physical layer (PHY)—physical coding sublayer (PCS) and physical media attachment (PMA) block.
The JESD204B IP core does not incorporate the Transport Layer (TL) that controls the frame assembly
and disassembly. The TL and test components are provided as part of a design example component where
you can customize the design for different converter devices.
