SERIAL INTERFACE
The AD7675 is configured to use the serial interface when the
SER/
PAR is held high. The AD7675 outputs 16 bits of data,
MSB first, on the SDOUT pin. This data is synchronized with
the 16 clock pulses provided on the SCLK pin.
MASTER SERIAL INTERFACE
Internal Clock
The AD7675 is configured to generate and provide the serial
data clock SCLK when the EXT/
INT pin is held low. The AD7675
also generates 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. The output data is valid on both the
rising and falling edge of the data clock. Depending on RDC/
SDIN input, the data can be read after each conversion, or
during the following conversion. Figure 17 and Figure 18 show
the detailed timing diagrams of these two modes.
Usually, because the AD7675 has a longer acquisition phase
than the conversion phase, the data is read immediately after
conversion. That makes the mode master, read after conversion,
the most recommended serial mode when it can be used.
