Overview
The TH80 is a dual channel high-speed digitizer
of very high input bandwith and up to 80MHz sampling
speed. A 32MB on-board DDR RAM allows the capture of
long burst at the full 80MHz sampling speed. Control
registers are mapped on the 32-bit OMNIBUS interface
and control is commanded via software on the host card.
The card can be used for fast signal digitizing between
1 and 80MSPS, acquiring gap-free burst length of up
to total on-board RAM capacity. Data can then be transferred
at the lower OMNIBUS rates to the mother board for post-processing
and/or bus-mastering to host PC memory. The A/D conversion
clock source is selected between an on-board oscillator
(default 80MHz) or an external TTL clock. Error correction
is performed in the logic with first order equation
where gain and offset coefficients can be written via
SW to on-board ROM.
