PRODUCT DE SCRIPT ION
T he AD8108 and AD8109 are high speed 8
×
8 video cross-
point switch matrices. T hey offer a –3 dB signal bandwidth
greater than 250 MHz and channel switch times of less than
25 ns with 1% settling. With –83 dB of crosstalk and –98 dB
isolation (@ 5 MHz), the AD8108/AD8109 are useful in many
high speed applications. T he differential gain and differential
phase of better than 0.02% and 0.02
°
respectively along with
0.1 dB flatness out to 60 MHz make the AD8108/AD8109 ideal
for video signal switching.
T he AD8108 and AD8109 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. T he AD8108 has a gain of +1, while the AD8109
offers a gain of +2. T hey operate on voltage supplies of
±
5 V
while consuming only 45 mA of idle current. T he channel switch-
ing is performed via a serial digital control (which can accommo-
date “daisy chaining” of several devices) or via a parallel control
allowing updating of an individual output without re-programing
the entire array.
T he AD8108/AD8109 is packaged in an 80-lead T QFP package
and is available over the extended industrial temperature range
of –40
°
C to +85
