Overview
The PTN3366BSMP, produced by NXP USA Inc., is a low-power, high-speed level shifter device designed for converting low-swing AC-coupled differential input signals to DVI v1.0 and HDMI v1.4b compliant open-drain current-steering differential output signals. This device supports up to 3 Gbit/s per lane, enabling the transmission of 36-bit deep color, 4K × 2K video format, or 3D video data. It features integrated active buffers and level shifters for the DDC (Display Data Channel) and HPD (Hot Plug Detect) signals, making it a versatile component for various display applications.
