GENERAL DESCRIPTION
The AD8106 and AD8107 are high speed, 16 × 5 video crosspoint
switch matrices. They offer a −3 dB signal bandwidth greater
than 260 MHz, and channel switch times of less than 25 ns
with 1% settling. With −78 dB of crosstalk and 97 dB isolation
(at 5 MHz), the AD8106/AD8107 are useful in many high speed
applications. The differential gain and differential phase of
greater than 0.02% and 0.02° respectively, along with 0.1 dB
flatness out to 60 MHz, make the AD8106/AD8107 ideal for
video signal switching.

Figure 1.
The AD8106 and AD8107 include five independent output
buffers that can be placed into a high impedance state for parallel-
ing crosspoint outputs, preventing off channels from loading the
output bus. The AD8106 has a gain of 1, while the AD8107
offers a gain of 2. Both operate on voltage supplies of ±5 V while
consuming only 30 mA of idle current. The channel switching is
performed via a parallel control, allowing updating of an individual
output without reprogramming the entire array.
The AD8106/AD8107 are offered in an 80-lead LQFP and are
available over the extended industrial temperature range of
−40°C to +85°C.

Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD8106/AD8107 is limited by the associated rise in junction
temperature. The maximum safe junction temperature for
plastic encapsulated devices is determined by the glass transition
temperature of the plastic, approximately 150°C. Temporarily
exceeding this limit can cause a shift in parametric performance
due to a change in the stresses exerted on the die by the package.
Exceeding a junction temperature of 175°C for an extended
period can result in device failure.
While the AD8106/AD8107 is internally short-circuit
protected, this may not be sufficient to guarantee that the
maximum junction temperature (150°C) is not exceeded under
all conditions. To ensure proper operation, it is necessary to
observe the maximum power derating curves shown in Figure 3.
