The MAX4886 evaluation kit (EV kit) is a fully assembled
and tested surface-mount printed-circuit board (PCB)
that contains two sub circuits, a typical 2:1 HDMI?
switch application (top half), and an eye diagram test
circuit (bottom half).
The MAX4886 HDMI application circuit evaluates the
MAX4886 high-speed HDMI/DVI? 2:1 digital video
switch, combined with the MAX4929E for lower frequency
signals, to provide a full 2:1 HDMI application
circuit. The EV kit operates from a 5V DC power supply
and provides on-board 3.3V regulation. HDMI input/output
connections are also provided to easily interface
with HDMI-compatible devices. All signal traces in the
HDMI application circuit are 100Ω differential controlled-
impedance traces.
A separate test circuit is also provided at the bottom of
the MAX4886 EV kit for eye diagram evaluation using
SMA connections and 50Ω controlled-impedance traces.
