JESD204B is a high-speed serial interface used between data converters, such as analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), and the FPGA device to replace traditional interfaces, such as CMOS and LVDS. With converter sampling rates and data throughput increasing, the JESD204B interface offers advantages in terms of size, cost, and speed.
The Lattice JESD204B IP supports both the Tx and Rx directions, with corresponding PHY, link, and embedded transport layers, on Lattice FPGA devices
JESD204B for Lattice Radiant – CertusPro-NX, Avant-G, Avant-X, and Certus-N2
JESD204B for Lattice Diamond – ECP5-5G, ECP5 and LatticeECP3.
