DS34RT5110-EVKH HDMI Extender Demo Kit for HDMI Cables General Description The DS34RT5110-EVKH HDMI Cable Extender Demo Kit provides a complete HDMI system extension solution using National’s DS34RT5110 - a DVI, HDMI Retimer with Input Equalization and Output De-Emphasis. Two HDMI female connectors are used as the input and the output connections for a HDMI system. The DDC signals are connected through an I2C buffer. The Hot Plug, 5V Power and 5V Ground are directly connected between the HDMI connectors, making this demo kit HDCP compliant. A 3.3V VCC 1-pin header (J22) and a GND 1-pin header (J23) are used for the power supply. Alternately, an AC/DC power adapter (>800mA) is required for the evaluation kit to provide 5V DC voltage for easy portability. A 1.8mm DC Power Jack is used to connect the AC/DC Power Adapter. National’s LP3965, a 3.3V, 1500mA, Fast, Ultra Low Dropout Linear Regulator, converts the 5V power supply voltage to a 3.3V power supply voltage that powers the DS34RT5110.
Features • • • • • • • •

Function The LED turns on when 5V DC applies The “GREEN” LED turns on when the incoming signal is detected by DS34RT5110 The “ORANGE” LED turns on when the PLL of the DS34RT5110 is locked Optional DC Power Jack for 1.5 mm Adaptor Plug
Connect JP48 to VDD to bypass Reclock function Connect JP52 to VDD to bypass the clock PLL function Turn the switch to control the EQ boost setting. “0” on the switch refers to the boost setting of “0X00”, “7” on the switch refers to the boost setting of “0X07”. See datasheet for detail Boost setting information. Turn the switch to control the DE setting. “0” = 0 dB, “1” = -3 dB, “2” = -6 dB, “3” = -9 dB, “4”, “5”, “6”, “7” = N/A

Layout Considerations • • •
Keep the clock and data transmission lines as short as possible with controlled 50 ohm single-ended impedance. Or, use differentially coupled traces with 100 ohm impedance. Avoid using vias on the clock and data transmission lines on the input side of the DS34RT5110. Place power supply decoupling capacitors close to the VCC pins.
