GENERAL DESCRIPTION
The AD8175 is a high speed, triple 16 × 9 video crosspoint
switch matrix. It supports 1600 × 1200 RGB displays @ 85 Hz
refresh rate, by offering a 500 MHz bandwidth and a slew rate
of 1800 V/µs. With −88 dB of crosstalk and −94 dB isolation
(@ 5 MHz), the AD8175 is useful in many high speed video
applications.
The AD8175 supports two modes of operation: differential-in
to differential-out mode with sync-on CM signaling passed
through the switch and differential-in to differential-out mode
responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other
rights of third parties that may result from its use. Specifications subject to change with out notice. No

with CM signaling removed through the switch. The output
CM and black level can be conveniently set via external pins.
The independent output buffers of the AD8175 can be placed
into a high impedance state to create larger arrays by paralleling
crosspoint outputs. Inputs can be paralleled as well. The
AD8175 offers both serial and parallel programming modes.
The AD8175 is packaged in a fully-populated 26 × 26 ball
PBGA package and is available over the extended industrial
temperature range of −40°C to +85°C.

POWER DISSIPATION
The AD8175 is operated with ±2.5 V or +5 V supplies and can
drive loads down to 100 Ω, resulting in a large range of possible
power dissipations. For this reason, extra care must be taken
derating the operating conditions based on ambient temperature.
Packaged in a 676-lead BGA, the AD8175 junction-to-ambient
thermal impedance (θ
the maximum allowed junction temperature of the die should
not exceed 150°C. Temporarily exceeding this limit may cause a
shift in parametric performance due to a change in stresses
exerted on the die by the package. Exceeding a junction
temperature of 175°C for an extended period can result in
device failure. The following curve shows the range of allowed
internal die power dissipations that meet these conditions over
the −40°C to +85°C ambient temperature range. When using
Table 12, do not include external load power in the Maximum
Power calculation, but do include load current dropped on the
die output transistors.
) is 15°C/W. For long-term reliability,
JA
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device
soldered in a circuit board for surface-mount packages.
