SERIAL INTERFACE
The AD7660 is configured to use the serial interface when the
SER/
PAR is held HIGH. The AD7660 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 AD7660 is configured to generate and provide the serial data
clock SCLK when the EXT/
INT pin is held LOW. The AD7660
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. Figures 16 and 17 show the detailed timing
diagrams of these two modes.
