IT6605数据手册ITE中文资料规格书

描述 Description

The IT6605 is a dual-port HDMI receiver, fully compatible with HDMI 1.3, compatible with HDMI 1.4a 3D and HDCP 1.4 and also backward compatible to DVI 1.0 specifications. The IT6605 with its Deep Color capability (up to 36-bit) ensures robust reception of high-quality uncompressed video content, along with state-of-the-art uncompressed and compressed digital audio content such as DTS-HD and Dolby TrueHD in digital televisions and projectors. The IT6605 also supports all the primary 3D formats which are compliant with the HDMI 1.4a 3D specification.Aside from the various video output formats supported, the IT6605 also receives and provides up to 8 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 provided to support up to compressed audio of 192kHz frame rate. Super Audio Compact Disc (SACD) is supported at up to 8 channels and 88.2kHz through DSD (Direct Stream Digital ports) ports.The High-Bit Rate (HBR) audio is also provided by the IT6605 in two interfaces: with the four I2S input ports or the S/PDIF input port. With both interfaces the highest possible HBR frame rate is supported at up to 768kHz.Each IT6605 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 IT6605 need not purchase any HDCP keys or ROMs.The IT6605 is pin compatible with the CAT6023, the previous HDMI 1.3 receiver.
