%description
cxadc is an alternative Linux driver for the Conexant CX2388x series of video decoder/encoder chips used on many PCI TV tuner and capture cards.

The new driver configures the CX2388x to capture in its raw output mode in 8-bit or 16-bit unsigned samples from the video input ports, allowing these cards to be used as a low-cost 28-54mhz 10bit ADC for SDR and similar applications.
