Features
HDMI active switch, providing superior performance over traditional passive switches
Compliant with HDMI 1.3 and DVI 1.0 standards
Serial data rate at up to 2.25Gbps, capable of supporting the following digital video formats in Deep
Color Mode at up to 36 bits (12 bits/color):
DTV resolutions: 480i, 576i, 480p, 576p, 720p, 1080i to 1080p
PC resolutions: VGA, SVGA, XGA, SXGA to UXGA
Single 3.3V operation
Internal AC-coupling at TMDS inputs to cope with uneven intra-pair DC levels of incoming TMDS
signals.
Embedded EDID RAM saves external EDID ROM costs
Embedded HDP resistors
Integrated HPD switches
Active port detection by monitoring PWR5V inputs and TMDS input clock.
DDC I2C repeater isolates backend DDC capacitive loading from frontend, enhancing the DDC
operation compatibility
Human Body Mode ESD protection up to ±8kV for all TMDS differential input pins
Disconnectable input terminations with auto-calibrated impedances
Adaptive input equalization supporting long and short cables at the same time
Software-mode operation providing flexibility
Two possible serial programming device address..
Programmable TMDS output current level
Programmable source terminations compliant with HDMI 1.3 standard, providing optimal source
data eyes at high speeds
High-impedance TMDS output when disabled
Optional backend receiver termination detection for auto powerdown
64-Pin LQFP package
RoHS Compliant ( 100% Green available )
