Hi all,


I have an application where I need to have longer cable, but the
chip that we are using only can drive 10cm cable length and I need
about 12 inches cable. Any idea what kind of buffers I need to drive
the signals to the other side without losing data?

Thanks,

SD

More details!


ST

p.s. WAY more details

with out any details its very hard to say but why dont you just try
it with the longer cable. 8 extra inches isn't going to make much of
a difference unless its a really tiny gauge wire and even then you
could go to a bigger gauge. We're talking V drop in low mVs if not
uVs. people often spec things *very* conservatively.

assuming its logic and you absolutely need buffers, just about any
buffer would do the trick. I'd look at CMOS since it can drive
closer to the rails - 74HC series would probably be ok.

You want longer wires? about 100 meteres? use a RS485 interface! lol!!
if that is too much for you, then follow the previows postings ;)

Hi
Send me the details of the cable U are using what type
of signal is it. Send signal parameters. It is posible
to amplify the signal using a step 2 amplifier but I
shd know the Vital Params first. Ill send U circuit.
Bye
