Figure 7. Demux Interleaved Mode Timing Diagram
Demux Interleaved Mode
Drive DEMUX high and ITL high to place the
MAX19542 in the demux interleaved mode of operation.
In this mode, the output clock’s frequency is 1/2 the
sampling frequency. The sampling frequency may not
be the same as the input clock frequency. See the
Divide-by-Two Clock Control (CLKDIV) section. Each
conversion starts with a sampling event on the rising
edge of CLKP. Conversion data now appears on both
DA0–DA11 and DB0–DB11. The first conversion result
is output on the A ports on the rising edge of DCLKP
after 12 input clock cycles from the initial sampling
event. The second conversion result is output on the B
ports on the rising edge of DCLKN after 12 input clock
cycles from the initial sampling event. In this way, the two
conversion results are interleaved with respect to each
other (Figure 7). The conversion results on ports A and B
remain stable for one period of DCLKP and DCLKN,
respectively, after they become valid. Overrange condi-
tions are reflected on the appropriate output port, ORA
or ORB, depending on which conversion they occur.
