MS9332C HD 1x2 Splitter IC
The MacroSilicon MS9332C is an HD signal 1x2 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 and 4K x 2K (YCbCr420) @ 60 Hz, with 10/12/16-bit color depth.
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.
