6.10.2 SFCO Interface Description
The simple full capacity output interface (SFCO) is a
3.072 MHz burst mode interface. It consists of a window,
data, errorflag and clock line. Furthermore, a serial sub-
channel identifier information is provided. The interface
carries fast information channel (FIC) and main service
information (MSC) at the output of the COFDM channel
decoder. The window line can be used to distinguish
between FIC and MSC data. Via the MC interface the
provided sub-channel can be selected. Only these
selected sub-channels are processed by the channel
decoder.
