MS9331
——————————————————————————————————————————————————————————
The
MS9331 is a HDMI retime IC that supports a signaling rate up to 3.0Gbps and I2S
& SPDIF output. With 3.0Gbps capability, the MS9331 can support the new
4K@30Hz video format and 4K (YCbCr420) @60Hz. The MS9331 equalizes incoming
TMDS data with optimal quality regardless of the incoming signal quality. The
highly acclaimed equalization technology provides for 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. The chip also
supports on-chip HDCP Keys RAM and EDID Memory.
