19-5707; Rev 0; 12/10 TION KIT EVALUA BLE IL AVA A Dual DisplayPort Graphics Multiplexer with HDMI Level Shifter General Description Features S Single +3.3V Supply S Meets HDMI v.1.4 Eye Mask Up to 2.25Gbps www.DataSheet4U.com MAX14886 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 compliance 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 DisplayPortK Interoperability Guideline v.1.1a-compliant (requires external DDC logic) and integrates seamlessly with an external HDMI connector on the motherboard. The device accommodates differential inputs as low as 200mV and drives transition minimized differential signaling (TMDS®) outputs to 1000mV (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 compliance, while maintaining full TMDS swing requirements. The device supports AC-(DisplayPort) 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 commercial temperature range, and is available in a 5mm x 5mm, 40-pin TQFN package. S Meets VESA DisplayPort Interoperability Guideline v.1.1a (Requires External DDC Logic) S Low-Power Shutdown Mode Active High or Active Low S Output Level Adjust (ADJ) for Output Back- Termination Without Amplitude Loss S Seamless Integration into Dual-Graphics Systems with External HDMI Connector DC-Coupled HDMI Outputs Mate Directly to HDMI Connector AC- or DC-Coupled TMDS-Formatted Inputs Ordering Information PART MAX14886CTL+ TEMP RANGE 0NC to +70NC PIN-PACKAGE 40 TQFN-EP* +Denotes a lead(Pb)-free/RoHS-compliant package. *EP = Exposed pad.

For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (VCC = +3.3V, TA = 0NC to +70NC, RADJ = 3.3kI, CCL = 100nF, typical values are at TA = +25NC.)
