AD7653
SLAVE SERIAL INTERFACE
External Clock
The AD7653 is configured to accept an externally supplied
serial data clock on the SCLK pin when the EXT/INT pin is held
HIGH. In this mode, several methods can be used to read the
data. The external serial clock is gated by CS. When CS and RD
are both LOW, the data can be read after each conversion or
during the following conversion. The external clock can be
either a continuous or a discontinuous clock. A discontinuous
clock can be either normally HIGH or normally LOW when
inactive. F
show the detailed timing
diagrams of these methods.

Figure 35. Slave Serial Data Timing for Reading (Read Previous Conversion during Convert)
While the AD7653 is performing a bit decision, it is important
that voltage transients be avoided on digital input/output pins,
or degradation of the conversion result could occur. This is
particularly important during the second half of the conversion
phase because the AD7653 provides error correction circuitry
that can correct for an improper bit decision made during the
first half of the conversion phase. For this reason, it is recom-
mended that when an external clock is being provided, it is a
discontinuous clock that is toggling only when BUSY is LOW,
or, more importantly, that it does not transition during the latter
half of BUSY HIGH.
