Providing
added convenience, the CEC feature allows
end users to use a single remote control
to run multiple CEC-enabled HD devices,
eliminating the need to juggle separate
remotes to control the TV, set-top box and
portable HD devices.
For
example, when viewing content from an HD
DVC, DSC, or portable media player on an
HDTV the CEC-enabled HDTV remote can be
used to play or rewind movies, manage power-on,
input selection and power-off functions
for the TV, cable/satellite set-top box
or audio/video receiver, switch between
boxes, or change video and audio modes.
The
ADV7520NK adds CEC support to the innovative
low-power design of ADI’s AD9387NK
HDMI transmitter, which enables longer-running
battery-powered video devices.
Unlike
competitive devices that can require external
voltage translator chips, ADI’s new
HDMI transmitter includes 5 V-tolerant I/Os
that support I²C and HPD (Hot Plug
Detect). This further simplifies system
design and extends battery life in portable
electronics by eliminating external voltage
translator chips to convert these I/O signals
from 5 V to either 1.8 V or 3.3 V.
