The 8964DEC offers four independent fullfunction 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.
