JESD204B Tx Controller IP

Description and Features

JESD204B interface provides full support for the JESD204B synchronous serial interface, compatible with JESD204B.01 version specification. Through its compatibility, it provides a simple interface to a wide range of low-cost devices. JESD204B Transmitter IIP is proven in FPGA environment. The host interface of the JESD204B can be simple interface or can be AHB, AHB-Lite, APB, AXI, AXILite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or Custom protocol. JESD204B Transmitter IIP is supported natively in Verilog and VHDL.
