OPERATION OF OUTPUT ENABLE  
Since the output enable, internal master oscillator and/or external master oscillator are likely all  
asynchronous there is the possibility of timing difficulties in the application. To minimize these  
difficulties the DS1075 features an “enabling sequencer” to produce predictable results when the device is  
enabled and disabled. In particular the output gating is configured so that truncated output pulses can  
never be produced.  
ENABLE TIMING  
The output enable function is produced by sampling the OE input with the output from the prescaler mux  
(MCLK) and gating this with the output from the programmable divider. The exact behavior of the  
device is therefore dependent on the setup time (tSU) from a transition on the OE input to the rising edge  
of MCLK. If the actual setup time is less than tSUEM then one more complete cycle of MCLK will be  
required to complete the enable or disable operation (see diagrams). This is unlikely to be of any  
consequence in most applications, and then only if the value for N is small. In general, the output will  
make its first positive transition between approximately one and two clock periods of MCLK after the  
rising edge of OE.  
FIGURE 4  
DISABLE TIMING  
If OE goes low while OUT is high, the output will be disabled on the completion of the output pulse. If  
OUT is low, the disabling behavior will be dependent on the setup time between the falling edge of OE  
and the rising edge of MCLK. If tSU < tSUEM the result will be one additional pulse appearing on the  
output before disabling occurs. If the device is in divide-by-one mode, the disabling occurs slightly  
differently. In this case if tSU > tSUEM one additional output pulse will appear, if tSU < tSUEM then two  
additional output pulses will appear.  
The following diagrams illustrate the timing in each of these cases.
