The MST3383MB integrates the HDMI compliant receiver for enabling advanced digital display
devices such as digital TVs, plasma displays, LCD TVs and projectors to receive and display.
Compliant with the HDMI 1.0 specification, the MST3383MB enables consumer electronic devices
to receive uncompressed, high quality, digital audio and video HD content over a single, low-cost
HDMI cable. The MST3383MB is available in a 128-pin PQFP package.
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
The MST3383MB provides 2-wire serial bus for interfacing with an MCU. It detects active inputs for
both on-line and off-line operations. During on-line operation, the MST3383MB also provides
polarity and period count information of active input’s DE signals. The MCU can easily adjust the
input mode and switch to active input properly.
Color Space Conversion
The MST3383MB supports all general color space conversions such as RGB to YUV or RGB to
YCbCr using parameters programmable by 2-wire serial bus.
Digital Video Output Formatting
The MST3383MB can output digital data in the following configurations:
. 24-bit 4:4:4 YCbCr/RGB output formats
. 16-bit 4:2:2 YCbCr output formats (ITU.601)
. 8-bit 4:2:2 YCbCr output formats (ITU.656)
. Channel swap
. MSB/LSB swap
