The MCT5100 M-DTV Module is intended to provide an "add-in" DTV reception
capability for existing analog TV set chassis designs.
accepts an analog IF signal that contains an 8-VSB modulated ATSC
transport stream. After filtering and amplification and fast AGC, the
signal is digitized in an ADC and then sent to a VSB demodulator. The
demodulated transport stream then sent to a DTV decoder where it is
first demultiplexed into the MPEG® video, audio, and other control/data
The MPEG video is then decoded onboard and driven to the
output video triple DAC and analog outputs. The audio stream is sent
to an audio processor where it is decoded and driven to a stereo
audio DAC and analog outputs.
Digital S/PDIF out is also provided for
Dolby Digital™ compliance. Overall control
and management of the DTV module rests with an onboard system controller
which interfaces to the host TV via a serial port.
