ASM1442 datasheet pdf


The ASM1442 is the high speed TMDS level shift ICs for High Definition Multimedia Interface (HDMI) and Digital Video Interface (DVI) video application. Those convert low-swing AC-coupled differential input from existing PCI Express in the chipset of PC to HDMI compliant differential output, supporting up to 3.4Gbps bandwidth of pixel data transition, as indicated in HDMI Rev1.4a. This conversion is automatic and transparent to the user. The devices operate at a single 3.3V supply. […]
