MAX14886 Datasheet | Maxim Integrated

Description Features S Single +3.3V Supply S Meets HDMI v.1.4 Eye Mask Up to 2.25Gbps .. The MAX14886 high-speed, low-skew, active redriver multiplexer is ideal for switching between outputs of dual-graphics systems and signal conditioning to meet HDMIK v.1.4 pliance up to 2.25Gbps at an external HDMI connector. It is used for switching between integrated (e.g., Intel or AMD) and discrete graphics (e.g., NVIDIA or ATI GPU). The device is VESA Display Port K Interoperability Guideline v.1.1a-pliant (requires external DDC logic) and integrates seamlessly with an external HDMI connector on the motherboard. The device acmodates differential inputs as low as 200m V and drives transition minimized differential signaling (TMDS®) outputs to 1000m V (typ). A precision resistor on the output level adjust pin (ADJ) allows differentiated output back-termination resistors of 400I (typ) to better meet HDMI mask jitter pliance, while maintaining full TMDS swing requirements. The device supports AC-(Display Port) or DC-(HDMI) coupling directly to the graphics IC and must be DC-coupled to the HDMI connector. In addition, the device features current backflow protection at the HDMI connector and a low-power, active-high or active-low shutdown mode. The device operates with a single +3.3V supply, is specified over the 0NC to +70NC mercial temperature range, and is available in a 5mm x 5mm, 40-pin TQFN package.
