Each product within this series is compliant with HDMI v1.4 specifications; a cutting-edge technology that supports Deep Color (10-bit and 12-bit) video in addition to 3D video resolutions (Frame Packing, Side by Side) and 4k UHD Formats.
The 1T-DA-670 series supports SDTV resolutions 480i/576i, HDTV resolutions to 1080p and 4k UHD resolutions to 4096×2160@24Hz and is HDCP compliant. In addition, these HDMI DA’s provide high bandwidth (up to 300MHz – 9Gbps) and provide signal amplification and equalization for high performance processing of audio and video allowing signals to travel great distances without quality loss. DVI 1.0 format is supported (using cable adapters) and the product provides automatic discovery of monitor EDID. A screw on power adapter cable prevents inadvertent disconnection of power and, as a bonus feature, all HDMI outputs can be cascaded to additional DA’s.
