Programmable DMUX Ratio
Additional Bit (IOR,IORN)
Clock Type Selection CLKTYPE and DRTYPE
The demultiplexer ratio is programmable through the RS ratio selection signal:
Table 3-3.
Figure 3-3.
Note:
Figure 3-4.
When a signal is applied on IOR and IORN, the additional bit is activated. It can be used to process the
out-of-range bit from the ADC, in which case the DMUX features an 11-bit input/output data stream.
IOR, IORN is demultiplexed by the selected DMUX ratio:
Note:
Two modes for the input and output clock type can be selected by way of the CLKTYPE and DRTYPE
single-ended digital inputs.
• In 1:4 ratio, AOR/DRAN, AORN/DRA, BOR/DRBN, BORN/DRB, COR/DRCN, CORN/DRC and
• In 1:2 ratio, AOR/DRAN, AORN/DRA and BOR/DRBN, BORN/DRB output this signal at half its initial
DOR/DRDN, DORN/DRD output this signal at a quarter of its initial speed.
speed.
Ports C & D data have undetermined level. They can be left unconnected.
In staggered output mode:
(AORN/DRA, AOR/DRAN), (BORN/DRB, BOR/DRBN), (CORN/DRC, COR/DRCN) and (DORN/DRD,
DOR/DRDN) are used as the Data Ready signal (output clock) for each port. In this mode the additional bit
is disabled.
