Part-No.: EP956, Function: Tx, Standard: HDMI / MHL

EP956 is a low power HDMI/MHL transmitter for resoltuions up to 1080p.

EP956 is a Low Power HDMI/MHL (High Definition Multimedia Interface/Mobile High-definition Link) transmitter. The chip is compliant with HDMI Rev 1.4, MHL Rev 1.0 and HDCP Rev 1.4 specifications. The chip converts input video data in RGB or YUV format and audio data in IIS or SPDIF format into HDMI/MHL differential signals. The chip supports 8-bit video upto 1080p in HDMI mode and 720p/1080i in MHL mode. The chip also supports 3D video. The chip supports highly flexible digital video input in a muxed 12-bits mode or non-muxed 24-bit mode input. In both modes, the chip supports single or dual edge clocking.
