Chapter 1.Overview
A framer device will retrieve the 8-KHz frame synchronization pulses and clock signals for
both transmit and receive sections. A time slot assigner will use these signals as inputs to
generate pulses or envelope signals for individual bit patterns, i.e., strobe signals for devices
without time slot assignment capability such as the MC68302, a rst-generation
communication processor.
For a backplane type of design without a synchronization to a network, the QMC devices
are capable of generating all necessary bus signals from their timers and baud-rate
generators. This design type is illustrated for a QUICC32 in Figure 1-9.
