IT66612: 1-to-2 HDMI Active Splitter with EDID RAM and Embedded MCU

The IT66612 is a one-to-two HDMI active splitter that supports a signaling rate of up to 3.0 Gbps. It is compatible with the latest HDMI 1.4b. With 3.0 Gbps capability, the IT66612 can support content stream such as the new 4K x 2K format, 1080P@120 Hz, 3D video with 1080P/3D@60 Hz in HDMI. Via IT66612, the ultra-high definition video content can be split to all its outputs.

To achieve a friendly remote control environment, the IT66612 provides a complete solution of HDMI CEC function. With IT66612’s embedded CEC hardware, developers could use high-level software API to implement all the necessary remote control commands easily.

The IT66612 equalizes incoming TMDS signal to optimal and outputs retimed data to downstream sinks. The highly acclaimed equalization technology of ITE TECH. INC. provides 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 IT66612 to save the cost of the external EDID ROMs. The process of downloading the EDID data into the RAM is simplified by firmware programming. Also, each IT66612 chip comes preprogrammed with a unique Source and a Sink HDCP key, in compliance with the HDCP 1.4 standard so as to provide secure transmission of high-definition content. Adopters are not required to purchase any HDCP keys or ROMs.

With embedded MCU and Flash, customers need no external Flash and MCU, which saves the BOM cost and board size.
