Intel® Agilex™ HDMI RX-TX Retransmit

12 Gbps (FRL) Simplex Parallel with FIFO buffer

Features

  • The design instantiates FIFO buffers to perform a direct HDMI video stream passthrough between the HDMI 2.1 sink and source.
  • The design comes with HDMI RX and TX instances.
  • The design demonstrates the insertion and filtering of Dynamic Range and Mastering (HDR) InfoFrame in RX-TX link module.
  • The design negotiates the FRL rate between the sink connected to TX and the source connected to RX. The design passes through the EDID from the external sink to the on-board RX in default configuration. The Nios® II processor negotiates the link base on the capability of the sink connected to TX. You can also toggle the user_dipsw on-board switch to manually control the TX and RX FRL capabilities.
  • The design includes several debugging features.
