And can support a color depth of 10/12/16 bits. The clock and data recovery function of the HDMI input end can be self-adaptive to wires with different lengths and different qualities, so that TMDS signals transmitted at high speed always have optimal performance. The HDMI output end has a signal pre-emphasis function and can support long-line transmission. The MS9332 integrates internal EDID RAM and HDCPKEY RAM.

MS9332 is an HDMI input, a dual HDMI output copy mode, for example 960×1080 input, and outputs 2 identical 960×1080 HDMI output pictures through the chip processing, as shown in fig. 3.
