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.

APPLICATIONS

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. The 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.

Routing of High Speed Signals Including:

Com posite Video (NTSC, PAL, S, SECAM.)

Com ponent Video (YUV, RGB)

Com pressed Video (MPEG, Wavelet)

3-Level Digital Video (HDB3)

P RO D UCT D ESCRIP TIO N

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

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°C.
