[ oooops.. forgot the tag, resending, sorry.. ]


Hellos,

I have a big FIFO chip covered by dust, that I'd like to finally use.
The most useful application I'm imagining for it is to finally make
myself a logic analyzer. This FIFO (Texas Instruments SN74V3690-6PEU)
is a 3.3V device, but has 5V tolerant inputs. "Great!" I thought.

What I'm asking you is: should I connect the probes (just a header
cable) directly to the FIFO, or should I use an high speed buffer
inbetween? Consider that the chip is specced at 166MHz.

Moreover, what is the cheapest way to produce a variable clock
speed up to 166MHz (and possibly beyond, for other applications)?
A PLL? Any chip you may suggest me?

Thanks!
TPM
