Patchable modulars

This brings up something I've been thinking about for a while....

2. computer control of all patches and parameters.



Check out the Harris matrix switcher IC's. The most dense unit I think they
offer has 128 analog switches that go from DC to 50 mhz with very little
non linearities over that range. 40 pin dip style or PLCC.
16X8 patchable, any or all switches on simultaneously and has a clear all
pin and built in latches.
Very low noise, offset and crosstalk too.

4 of them could be a 32 x 16 patcher or a 64 x 8. There are lots of
possibilities.


P/N is CD22M3494E

They cost less than 8 dollars each.

In fact, Harris was kind enough to send me 10 of them as samples for no
charge whatsoever.

Mitel makes a duplicate of this chip as well.
