MS9334C HD 1x4 Splitter IC
The MacroSilicon MS9334C is an HD signal 1x4 splitter IC with a maximum signal rate of 3 Gbps. At 3 Gbps, it supports HD input resolutions up to 4K x 2K @ 30 Hz, with 10/12/16-bit color depth and YCbCr420 4K x 2K @ 60 Hz format support.
The HD input includes clock and data recovery with adaptive EQ. The HD output provides signal pre-emphasis for longer cable runs. The chip integrates internal EDID RAM.
