ASM 1443

ASM1443 is a six channel multiplexer integrated with HDMI/DVI level shifter to switch HDMI/DVI signals or PCI Express signals. It provides four differential data signals and also switches Hot Plug signals as well as the AUX+/- signals. ASM1443 is a single chip for HDMI/DVI switch solution. It is designed to support high definition video output for HDMI and DVI. The bandwidth of data rate is up to 2.5Gbps. The signals of ASM1443 are low attenuation signal quality with low bit-to-bit skew and high channel-to-channel noise isolation..
