PRODUCT DESCRIPTION
AD8151 is a member of the Xstream line of products and is
a breakthrough in digital switching, offering a large switch array
(33 × 17) on very little power, typically less than 1.5 W. Addi-
tionally, it operates at data rates in excess of 3.2 Gb/s per port,
making it suitable for Sonet OC-48 with 8b/10b Forward Error
Correction (FEC). Further, the pricing of the AD8151 makes
it affordable enough to be used for lower data rates as well.
The AD8151’s flexible supply voltages allow the user to operate
with either PECL or ECL data levels and will operate down to
3.3 V for further power reduction. The control interface is CMOS/
TTL compatible (3 V to 5 V).
Its fully differential signal path reduces jitter and crosstalk while
allowing the use of smaller single-ended voltage swings.
The AD8151 is offered in a 184-lead LQFP package that operates
over the extended commercial temperature range of 0°C to 85°C.

AD8151–SPECIFICATIONS
(@ 25�C, VCC = 3.3 V to 5 V, VEE = 0 V, RL = 50 � (see TPC 22), IOUT = 16 mA, unless
otherwise noted.)
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD8151 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the AD8151
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 may 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.
To ensure proper operation, it is necessary to observe the maxi-
mum power derating curves shown in Figure 2.
