PRODUCT DESCRIPTION
AD8150 is a member of the
X
stream
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 1.5 Gbps per port,
making it suitable for HDTV applications. Further, the pric-
ing of the AD8150 makes it affordable enough to be used for
SD applications as well. The AD8150 is also useful for OC-24
optical network switching.
The AD8150’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 AD8150 is offered in a 184-lead LQFP package that operates
over the industrial temperature range of 0
°
C to 85
°
C.
