MASTER SERIAL INTERFACE
Internal Clock
The AD7671 is configured to generate and provide the serial data
clock SCLK when the EXT/
INT pin is held LOW. It also gener-
ates a SYNC signal to indicate to the host when the serial data is
valid. The serial clock SCLK and the SYNC signal can be inverted
if desired. Depending on RDC/SDIN input, the data can be read
after each conversion or during conversion. Figures 17 and 18
show the detailed timing diagrams of these two modes.
Usually, because the AD7671 is used with a fast throughput, the
mode master, read during conversion, is the most recommended
Serial Mode when it can be used.
In Read-during-Conversion Mode, the serial clock and data toggle
at appropriate instants, which minimizes potential feedthrough
between digital activity and the critical conversion decisions.
In Read-after-Conversion Mode, it should be noted that unlike
in other modes, the signal BUSY returns LOW after the 16 data
bits are pulsed out and not at the end of the conversion phase,
which results in a longer BUSY width.
While the AD7671 is performing a bit decision, it is important that
voltage transients not occur on digital input/output pins or degra-
dation of the conversion result could occur. This is particularly
important during the second half of the conversion phase because
