11 / 32 page  T5761 T5760 / Preliminary Information Rev. A2, 19-Oct-00 11 (32) Digital Signal Processing The data from the ASK/ FSK demodulator (Dem_out) is digitally processed in different ways and as a result con- verted into the output signal data. This processing depends on the selected baud-rate range (BR_Range). Figure 14 illustrates how Dem_out is synchronized by the extended clock cycle TXClk. This clock is also used for the bit-check counter. Data can change its state only after TXClk has elapsed. The edge-to-edge time period tee of the Data signal as a result is always an integral multiple of TXClk. The minimum time period between two edges of the data signal is limited to tee ≥ TDATA_min. This implies an effi- cient suppression of spikes at the DATA output. At the same time it limits the maximum frequency of edges at DATA. This eases the interrupt handling of a connected µC. The maximum time period for DATA to stay Low is lim- ited to TDATA_L_max. This function is employed to ensure a finite response time in programming or switching off the receiver via Pin DATA. TDATA_L_max is thereby longer than the maximum time period indicated by the transmit- ter data stream. Figure 16 gives an example where Dem_out remains Low after the receiver has switched to receiving mode. Clock bit–check counter Data_out (DATA) T XClk Dem_out t ee Figure 14.
