Quick Start Table 1. Jumper JU1 Functions SHUNT POSITION MAX4886 SEL PIN SIGNAL PATH Recommended Equipment Before beginning, the following equipment is needed: 1-2* Connected to VDD J3 to J1 One or two HDMI sources 2-3 Connected to GND J2 to J1 *Default position. HDMI-compatible sink (e.g., monitor) Input Supply and On-Board Regulation Procedure Jumper JU2 selects between the MAX4886 EV kits The MAX4886 EV kit is a fully assembled and tested power-up options, either through the HDMI source surface-mount PCB. Follow the steps below to verify the applied at J2/J3 or an external 5V DC power supply. To board operation: configure these options, set JU2 as desired (see Table 2). 1) Verify that a shunt is installed across pins 1-2 on The MAX6329 then converts the voltage from 5V (V+) to jumpers JU1, JU2, and JU3. 3.3V (VDD) to power the MAX4886 and MAX4929E (top 2) Connect one or two HDMI sources to J2 and/or J3. half). Note that when powering from a regulated exter- nal 5V supply, make sure to apply power before the 3) Connect an HDMI-compatible sink to J1. HDMI signal is applied. 4) Enable the HDMI source(s). Table 2. Jumper JU2 Functions Detailed Description SHUNT POSITION EV KIT INPUT SUPPLY The MAX4886 EV kit is a fully assembled and tested 1-2* Supplied from HDMI source surface-mount PCB. The MAX4886 EV kit comprises 2-3 Externally supplied to +5V pad two circuits, a typical HDMI 2:1 switch, and an eye dia- gram test circuit. *Default position. The HDMI application circuit evaluates the MAX4886 MAX4929E Enable Input (HIZ2) high-speed HDMI/DVI 2:1 digital video switch, combined The MAX4929E is enabled through configuration of the with the MAX4929E, to perform a full 2:1 HDMI switching HIZ1 and HIZ2 pins. Jumper JU3 controls the function. On the EV kit, the typical 2:1 HDMI switching MAX4929Es enable input on the EV kit by controlling circuit (top half) can be self-powered from the HDMI the HIZ2 pin. By configuring JU3 to the desired setting source or from an external regulated 5V source and pro- (see Table 3), the MAX4929E can be set for normal vides on-board 3.3V regulation to power the switching operation or placed in a high-impedance state. Note circuit. All signal traces in the HDMI application circuit that the MAX4929Es HIZ1 pin is set to GND by default. are 100 differential controlled-impedance traces. A separate test circuit is also provided at the bottom of Table 3. Jumper JU3 Functions the MAX4886 EV kit for eye diagram evaluation using SHUNT MAX4929E HIZ2 PIN FUNCTION SMA connections and 50 controlled-impedance traces. POSITION Logic Inputs (SEL) Normal operation 1-2* Connected to VDD The MAX4886 SEL pin controls the signal paths (enabled) between source 1 and source 2. By setting jumper JU1 High-impedance (see Table 1), SEL can be configured to set the signal 2-3 Connected to GND mode (disabled) path either from J3 to J1 or from J2 to J1. *Default position. 2 Evaluates: MAX4886
