TIMING DIAGRAMS
Busy Output
The state of converter is indicated by the state of the BUSY out-
put (Pin 44). The BUSY output will go HI at the negative edge
of the STROBE input. This is used to synchronize digital input
data and load the digital angular rotation information into the
device counter. The BUSY output will remain HI for 2
µs, and
go LO until the next strobe negative edge occurs.
Strobe Input
The width of the positive STROBE pulse should be at least
100 ns, in order to successfully start the conversion. The maxi-
mum frequency of STROBE input is 366 kHz, i.e., there should
be at least 2.73
µs from the negative edge of one STROBE pulse
to the next rising edge. This is illustrated by the following tim-
ing diagram and table.

APPLICATIONS
Forward and ReverseTransformation
The AD2S100 can perform both forward and reverse transfor-
mations. The section “Theory of Operation” explains how the
chip operates with the core operator e
+j
φ, which performs a for-
ward transformation. The reverse transformation, e
–j
φ, is not
mentioned in the above sections of the data sheet simply to
avoid the confusion in the functionality and pinout. However,
the reverse transformation is very useful in many different appli-
cations, and the AD2S100 can be easily configured in a reverse
transformation configuration. Figure 9 shows four different
phase input/output connections for AD2S100 reverse transfor-
mation operation.
