JESD204B Tx Controller IP

Description and Features

The JESD204B interface offers complete support for the synchronous serial JESD204B interface, which is compliant with the JESD204B.01 version standard. It offers a user-friendly interface to a variety of inexpensive devices due to its interoperability. In an FPGA context, the JESD204B Transmitter IIP has been tested. The JESD204B's host interface options include a basic interface, an AHB, AHB-Lite, an APB, an AXI, an AXILite, a Tilelink, an OCP, a VCI, an Avalon, a PLB, a Wishbone, or a custom protocol. Verilog and VHDL both have native support for JESD204B Transmitter IIP.
