Description
The kit consists of following boards for different application needs:
•
The DS22EV5110 receiver board with RJ45-in and HDMI-out connectors (
Board ID: 551600199-022
)
•
A passive adapter board with RJ-45 and HDMI connectors (
Board ID: 980013178
)
The DS22EV5110 receiver board has two RJ45 jacks as the inputs and one HDMI female receptacle
connector as the output.
The passive adapter board has two RJ45 jacks and one HDMI female receptacle connector. Either can be
the input(s) or the output(s).
The DS22EV5110 on the boards equalizes the long reach HDMI or CAT5 cable at the input, and then
sends out the low jitter TMDS signal to the HDMI cable through output.
All of the TMDS signals are connected through one RJ45 jack between two boards.
The DDC signals are connected through an I2C buffer. The hot plug, 5V power and 5V ground are directly
connected between the connectors, making this demo kit HDCP compliant.
A 3.3V VCC 1-pin header and a GND 1-pin header are used for the power supply for the DS22EV5110
boards.
Alternately, an AC/DC power adapter (>800 mA) can be used for each driver or receiver board of the
evaluation kit to provide 5V DC voltage for easy portability. A 1.8 mm DC power jack is used to connect
the AC/DC power adapter. Texas Instruments LP3965, a 3.3V, 1500 mA, fast, ultra low dropout linear
regulator, converts the 5V power supply voltage to a 3.3 V power supply voltage that powers the
DS22EV5110.
