The MAX14886 evaluation kit (EV kit) provides a proven
design to evaluate the MAX14886. This high-speed, low-
skew, active redriver multiplexer is ideal for switching
between outputs of dual-graphics systems and signal
conditioning to meet High-Definition Multimedia Interface
(HDMIK) v1.4 compliance up to 2.25Gbps at an external
HDMI output connector. The EV kit contains three sec-
tions: an application circuit, characterization circuit, and
calibration traces.
The application circuit is designed to demonstrate the
device in multiplexing and redriving TMDS
dual-mode DisplayPortK signals into an HDMI output
connector. This section of the EV kit operates from a +5V
USB supply that is regulated by an on-board +3.3V LDO
regulator, which powers the U1 device and companioned
DDC logic (U3). All signal traces in the application circuit
are 100I differential controlled-impedance traces.
The characterization circuit is provided for eye diagram
evaluation using SMA connectors, controlled-impedance
traces, and output bias-Ts to interface with standard 50I
test equipment. This section is powered by an external
+3.3V power supply.
The calibration traces match the length and shape of the
input traces in the characterization circuit (U4) for further
high-frequency analysis.
