GENERAL DESCRIPTION
The AD8146/AD8147/AD8148 are high speed triple, differential or
single-ended input to differential output drivers. The AD8146
and AD8147 have a fixed gain of 2, and the AD8148 has a fixed
gain of 4. They are all specifically designed for the highest
resolution component video signals but can be used for any
type of analog signals or high speed data transmission over
either Category 5 UTP cable or differential printed circuit
board (PCB) transmission lines.
These drivers can be used with the AD8145 triple differential-
to-singled-ended receiver, and the AD8117 crosspoint switch to
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).
The common-mode voltage of each AD8146 output can be set
to any level, allowing transmission of signals over the common-
mode voltages. The AD8147 and AD8148 encode the vertical
and horizontal sync 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.
The AD8146/AD8147/AD8148 are available in a 24-lead LFCSP
and operate over a temperature range of −40°C to +85°C.
