Triple Differential Drivers for
Wideband Video
These drivers can be used with the
to single-ended receiver, and the
produce a video distribution system capable of supporting UXGA
or 1080p signals.
Manufactured on the Analog Devices, Inc., second generation
XFCB bipolar process, the drivers have large signal bandwidths
of 700 MHz and fast slew rates. They have an internal common-
mode feedback feature that provides output amplitude and phase
matching that is balanced to −60 dB at 50 MHz, suppressing even
order harmonics and minimizing radiated electromagnetic
interference (EMI).
Both the
AD8147
signals on the common-mode voltages of the outputs. All outputs
can be independently set to low voltage states to be used with series
diodes for line isolation, allowing easy, differential multiplexing
over the same twisted pair cable.
AD8147
The
AD8147/AD8148
operate over a temperature range of −40°C to +85°C.
This user guide provides all supporting documents for evaluating
the AD8147/AD8148. Consult the
sheets, which provide additional information, when working with
the evaluation board.
