The 8964DEC offers four independent full-
function decoders on a single Gecko series
card. Typical applications include cost-effective
analog conversion for a digital server, switcher,
or router. Up to 40 decoders can be housed in
only 2 RU of space.
The 8964DEC has a robust analog input
circuit, which easily accommodates noisy
signals such as satellite and microwave
links. Most adjustments to this card can be
performed on the module's card-edge controls.
The on-screen display capability included with
each module greatly simplifies card-edge
configuration.
