Jumper JU3 to connect the board supply to the wall plug supply (WWART). 2) For DVI use, connect the input cable/board to the DVI input and connect a DVI monitor or DVI receiver to the MAX3814 EV kit output. Change jumper JU1 to enable DVI equalizer. Jumper JU2 can remain disabled. The default setting is LEVEL = 1 with 200 back terminations. 3) For HDMI use, connect the cable or board to the HDMI input and connect a monitor or receiver to the HDMI output. Change jumper JU2 to enable the HDMI equalizer. The default setting is LEVEL = 1 with 200 back terminations. Other Adjustments 1) To choose the lower power (LEVEL = 0) setting without the 200 back termination resistors, remove resistors R1, R2, R3, R4, and R5 for DVI channel. Install a 0 resistor for R6. For the HDMI channel, remove R7, R8, R9, R10, and R11. Install a 0 resistor for R12. 2) To use a separate 3.3V supply, move the supply select jumper (JU2) to the "EXT" position. Then connect the 3.3V supply V CC to J4 (3.3V) and ground to J5 (GND). See Figure 2. Scope Measurements The DVI and HDMI connectors make it difficult to make electrical measurements with an oscilloscope that has SMA connectors. To make such measurements with the MAX3814 EV kit, adapter boards can be purchased from Tektronix. The part numbers are DVI-TPA-R-DI for the DVI socket and HDMI-TPA-P for the HDMI socket. You can also contact Maxim's Customer Applications Group for the MAX3814 to get adapter board layouts. Table 1. Adjustment and Control Descriptions (See Quick Start First) NAME JU3 FUNCTION Selects external power supply or wall plug switching power supply (WWART). JU1 Selects enable/disable for DVI channel. JU2 Selects enable/disable for HDMI channel. ________________________________________________________________ Maxim Integrated Products For pricing, delivery, and ordering information, please contact Maxim Direct at 1-888-629-4642, or visit Maxim's website at www.maxim-ic.com. 1 Evaluates: MAX3814 General Description Evaluates: MAX3814 MAX3814 Evaluation Kit R1 200 U2 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 U3 N.C.
