phase of better than 0.02% and 0.02掳 respectively, along with
0.1 dB flatness out to 60 MHz, make the AD8110/AD8111 ideal
for video signal switching.
The AD8110 and AD8111 include eight independent output
buffers that can be placed into a high impedance state for paral-
leling crosspoint outputs so that off channels do not load the
output bus. The AD8110 has a gain of +1, while the AD8111
offers a gain of +2. They operate on voltage supplies of
卤
5 V
while consuming only 50 mA of idle current. The channel
switching is performed via a serial digital control (which can
accommodate 鈥渄aisy chaining鈥?of several devices) or via a paral-
lel control, allowing updating of an individual output without re-
programing the entire array.
The AD8110/AD8111 is packaged in an 80-lead TQFP package
and is available over the extended industrial temperature range
of 鈥?0掳C to +85掳C.
The AD8110 and AD8111 are high speed 16

8 video cross-
point switch matrices. They offer a 鈥? dB signal bandwidth
greater than 260 MHz, and channel switch times of less than
25 ns with 1% settling. With 鈥?8 dB of crosstalk and 鈥?7 dB
isolation (@ 5 MHz), the AD8110/AD8111 are useful in many
high speed applications. The differential gain and differential
