AV Switcher solution development IC Chip
This product uses the NX9261 audio and video switching processing
chip, which routes four sets of audio and video signals to one set
of audio output through the I2C digital interface and
high-performance control processor NX6316. Its typical applications
include satellite set-top boxes, high-definition televisions
(HDTVs), personal video recorders (PVRs), A/V switches, security
devices, media centers, and in car entertainment systems, routing
multiple devices to a single audio and video device.
The NX9261 audio and video switching processing chip provides four
sets of audio and video inputs, which are routed to one set of
audio and video outputs through the core processor. Input to output
routing is controlled through an I2C compatible digital interface.
Each input supports an integrated clamping option to set the output
to synchronize the video's tip level to 300mV. Alternatively, the
input can be internally biased to the center signal without
synchronization of approximately 1.25V (chromaticity, Pb, Pr).
These DC output levels are used for 6dB gain setting. A higher gain
setting will increase the corresponding level of DC output. Select
input clamping/bias mode via I2C. Unused outputs may lose power to
reduce power consumption.
