GENERAL DESCRIPTION
AD8150 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.
Additionally, it operates at data rates in excess of 1.5 Gbps per
port, making it suitable for HDTV applications. Further, the
pricing of the AD8150 makes it affordable enough to be used
for SD applications. 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.
