General Description
provided to support up to compressed audio of 192kHz frame rate.
The IT6801FN is a single-port HDMI receiver which can operate in both HDMI1.4 and MHL2.1 dual
mode, it is fully compatible with MHL2.1, HDMI 1.4b, HDMI 1.4b 3D and HDCP 1.4 and also backward
compatible to DVI 1.0 specifications. The IT6801FN with its Deep Color capability (up to 36-bit)
ensures robust reception of high-quality uncompressed video content. The IT6801FN also supports all
the primary 3D formats which are compliant with the HDMI 1.4b 3D specification.
Each IT6801FN comes preprogrammed with an unique HDCP key, in compliance with the HDCP 1.4
standard so as to provide secure transmission of high-definition content. Users of the IT6801FN need
Aside from the various video output formats supported, the IT6801FN also receives and provides up to
4 channels of I2S digital audio outputs, with sampling rate up to 192kHz and sample size up to 24 bits,
facilitating direct connection to industry-standard low-cost audio DACs. Also, an S/PDIF output is
