DisplayPort-to-HDMI/DVI level shifter supports legacy displays

Sunnyvale, Calif.—Maxim Integrated Products has introduced the MAX9406, a fast, low-skew, quad-channel DisplayPort-to-HDMI/DVI level shifter that enables PCs with a DisplayPort output to directly drive an HDMI/DVI-capable display, such as an LCD screen.

The MAX9406 provides PC and graphics card manufacturers the flexibility to design for the DisplayPort specification, while supporting legacy HDMI/DVI displays through a low-cost level shifter. Additionally, it can level shift a differential video data stream driven through a PCI Express card to drive an HDMI/DVI display. This capability enables alternate PC motherboard configurations, such as an add-on HDMI/DVI PCIe-based solution.

The MAX9406 provides 5V to 3.3V bidirectional level shifting for the I²C-compatible display data channel (DDC) pins and 5V to 3.3V level shifting for the hot-plug detection (HPD) pin. This high-performance device features low 0.56psRMS added random jitter, a 2Gbit/s (max) data rate, an ultra-low 350ps propagation delay, and channel-to-channel skew of 20ps. Additionally, the inputs integrate 50 ohm terminations and a self-biased common mode. The 48-pin version of the MAX9406 is function and pin compatible with the Intel HDMI level-shifter specification.

Available in space-saving, 5mm x 5mm, 32-pin and 7mm x 7mm, 48-pin TQFN packages, the MAX9406 is fully specified over the -40°C to +85°C extended temperature range.
