FUNCTIONAL DESCRIPTION
DVI/HDMI Interface
The MST3383MB integrates an HDMI compliant receiver and enables a high quality and secure
delivery of digital video and audio. The HDMI link input supports up to 170 MHz pixel rate. With the
HDMI input and signal detection, the MST3383MB provides a high-performance solution for up to
1080p for video and 1600x1200 (UXGA) for monitor applications. The MST3383MB’s HDMI
receiver is fully backward compatible to DVI 1.0 and HDCP 1.0.
MCU Interface
