Application Examples
APPLICATION EXAMPLES
The MC68177 IC connects to a receiver capable of converting a 4 level audio signal into a 2-bit
digital signal. The FLEX decoder IC has eight receiver control lines used for warming up and
shutting down a receiver in stages. The FLEX decoder IC has dual bandwidth control signals for
two post detection Tlter bandwidths for receiving the two symbol rates of the FLEX signal. The
FLEX decoder IC has the ability to detect a low battery signal during the receiver control
sequences. It interfaces to a host MCU through a standard SPI. It has a 38.4 kHz clock output
capable of driving other devices. It has a one minute timer that offers low-power support for a
time-of-day function on the host.
