MAX3815A is a HDMI/DVI digital video equalizer from Maxim that automatically compensates for DVI™ and HDMI™ v1.3 cables, extending the usable cable distance up to 40 meters (1.65Gbps) and 35 meters (2.25Gbps).
The MAX3815ATMDS is a SiGe‑BiPolar digital video equalizer designed for HDMI/DVI v1.3 cables. It automatically compensates for skin‑effect loss, providing up to 40 m (1.65 Gbps) or 35 m (2.25 Gbps) of usable cable length. The device features four CML differential inputs and outputs, a loss‑of‑clock (LOS) detector, and selectable output drive levels.
Typical applications include HDMI/DVI inputs for projectors, HDTVs, computer monitors, cable‑extender modules, and active cable assemblies. The part is supplied in a 7 mm × 7 mm, 48‑pin TQFP‑EP package and operates from –55 °C to +150 °C. Layout recommendations emphasize short, direct traces, proper grounding, and 100 Ω differential impedance to maximize performance.
