MAX14886CTL+

Video Processing Overview

The MAX14886CTL+ is a dual DisplayPort graphics multiplexer with an integrated HDMI level shifter, designed for switching between dual-graphics system outputs. It operates on a single +3.3V supply within the 0°C to +70°C commercial temperature range. The device accommodates differential inputs as low as 200mV and drives TMDS outputs to 1000mV (typ). It supports data rates up to 2.25Gbps, meeting HDMI v.1.4 eye mask compliance. Key electrical parameters include a typical supply current of 52.5mA, shutdown current of 100µA, and propagation delay of 250ps. It features lane-to-lane skew of 50ps and deterministic jitter of 0.04 UI.

Video Processing FAQ

How is the output back-termination resistance adjusted?

The output back-termination is adjusted using a precision resistor connected to the ADJ pin. A typical value of 3.3kΩ sets standard operation, while decreasing this value allows for 400Ω back-termination to improve jitter compliance.

What coupling methods are supported for inputs?

The device supports both AC coupling for DisplayPort sources and DC coupling for HDMI sources. Inputs have internal 50Ω terminations to VCC, allowing direct connection to either source type.
