DisplayPort to DVI™/HDMI Level Shifter

High-Speed DisplayPort to DVI/HDMI Level Shifter

Please check latest availability status for a specific part variant.


The MAX9406 high-speed, low-skew, quad differential input to current-mode logic (CML) translator features high-speed signal conversion of the DisplayPort™ (DP) to High-Definition Multimedia Interface (HDMI™) technology. This device features ultra-low propagation delay of 350ps and channel-to-channel skew of less than 20ps. The MAX9406 supports typical data rates of 2Gbps.

The MAX9406 provides the level shift for HDMI's Display Data Channel (DDC) and hot-plug detection (HPD), which converts the 5V single-ended logic to 3.3V single-ended logic.

The MAX9406 operates from a 3V to 3.6V core supply and is specified over the -40°C to +85°C extended temperature range. This device is available in 48-pin, 7mmx 7mm thin QFN and 32-pin, 5mm x 5mm thin QFN packages.
