IT6664
产品详情
The IT6664 is a one-to-four HDMI 2/MHL dual-in, HDMI 2 out active splitter that supports a signaling rate up to 6.0 Gbps per channel. It is compatible with the latest HDMI 2.0, MHL 2.2, and HDCP 2.2 specifications. The 6.0 Gbps bandwidth capability of IT6664 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 TX and RX side of IT6664 such that HDMI 2.0 content could be properly received and transmitted to downstream side.
To facilitate system design, IT6664 integrates on-chip CSC conversion (including YCbCr 420/422/444 up or down and RGB/YCbCr conversion), and 4:1 down-sampling function, such proper video stream could be output to each of the connected display device according to its EDID and cable length.
The installed HDCP 2.2 engines and keys on both receiving and transmitting side make IT6664 possible to act as an HDCP 2.2/1.x Repeater or an HDCP 2.2 to 1.x/HDCP 1.x to 2.2 converter, eliminating HDCP compatibility issue. Note, the HDCP 2.2 to 1.x conversion is restricted for closed system application.
To achieve a friendly remote control environment, the IT6664 provides a complete solution of HDMI CEC function and MHL RCP function as well. With IT6664's embedded CEC/RCP hardware, developers could use high-level software API to implement all the necessary remote control commands easily.
The IT6664 equalizes incoming TMDS signal to optimal and outputs retimed data to downstream sinks. The highly acclaimed equalization technology of ITE TECH. INC. provides for support of long or low-quality HDMI cables at even the highest speeds. Input terminations of the TMDS inputs and output current levels are both programmable.
An EDID RAM is embedded in IT6664 to save the cost of the external EDID ROMs. The process of downloading the EDID data into the RAM is simplified by firmware programming.
The IT6664 operates in software mode that allows the system to control it via a two-line serial interface, PCSCL/PCSDA. Two serial programming addresses can be selected by PCADR.
