IT66631: HDMI 2.0-to-HDMI 2.0/TTL Dual Output Converter

The IT66631 is a one-to-two, HDMI 2.0 to HDMI 2.0/TTL converter that supports a signaling rate of up to 6.0 Gbps per channel on the HDMI interface. It is compatible with the latest HDMI 2.0 and HDCP 2.3 specifications. The 18.0 Gbps bandwidth capability of IT66631 allows it to support content stream such as the popular ultra-high definition 4K x 2K 60 Hz format, 3D video with 4K x 2K@30 Hz, and so on. SCDC data structure is contained in both HDMI RX and HDMI TX side of IT66631 such that HDMI 2.0 content could be properly received and transmitted to downstream side. The 48-bit TTL outputs of IT66631 make solutions with HDMI interface and TTL-in video processors possible.

To facilitate system design, IT66631 integrates on-chip CSC conversion (including YCbCr 420/422/444 up or down and RGB/YCbCr conversion) and 4:1 down-sampling function, and thereby proper video stream could be output to HDMITX and TTL. The 4:1 down-sampling function is especially useful for those applications
