HDMI 1.4 Tx PHY IP in 28HPC

Description and Features

IP core that completely conforms with HDMI 1.4 requirements for physical layer HDMI transmitters For consumer electronics like DVD player/recorders and camcorders, the HDMI transmitter PHY offers an easyto-implement system LSI solution that supports pixel clocks between 25MHz and 250MHz. The following Fab/Nodes have all undergone Silicon Proving: (TSMC, UMC, SMIC, GF, Samsung, ST). It will be straightforward to integrate the HDMI Transmitter Link IP Core into the SoC of consumer goods because it supports HDMI 1.4b and runs at 2.25 Gbps, 16-bit deep colour, and 3D compatibility (HD-TV, AV receiver... etc.). Linking the HDMI Rx IP to the HDMI Transmitter PHY IP will give it the optimum performance, features, and efficiency. Various HDMI Tx IP configurations are available.
