Hello all,
I am in the middle of laying out a design for a medical device the reads
in data pretty quickly (~20MHz) in bursts, but is limited to a slow serial
connection to transfer the data. The solution that comes to my mind is a
large FIFO buffer (~100k+) that can take an 8-bit parallel input, but I
can't find them anywhere in a reasonable price range. I've looked all over
at the common manufactures of logic devices (TI,nationalsemi) and some
distributors (digikey,mouser) but can't find much. I hear of hard drives
with 512k buffers/caches quite commonly. what am I missing here?
Does anyone know of a model/part# of a pretty high speed, 100k+ fifo
buffer?
Thanks in advance for your help.
Best Regards,
Adam Kumpf
