Hi all, I am working on another PIC-based instrument. Could someone please point me to some information about analog shift registers? I am looking for something like the Panasonic Bucket Brigade Devises in Digi-Key catalog. I have contacted the Panasonic rep (will call back soon?) and asked for information on those parts. I am interested in max clock rate, etc.. I remember seeing something similar many years ago but I can not find info in our databook library (it would help if I could remember who the manufacturer was). In my application, I need to delay a Gaussian-like pulse of width approx 5uSec for a delay that may vary (from one user configuration to the next) from 5uSec to 20uSec. Minimal amplitude and shape distortion of the pulses is very important. Any suggestions?? Mark A.
