AD7827 SERIAL INTERFACE
In order to achieve a high throughput rate, the serial port of the
AD7827 has been optimized for high speed serial protocols.
Many high speed serial protocols use a continuous serial clock
to transfer data, e.g., the serial ports of many popular DSPs like
the TMS320C5x, ADSP-21xx and DSP560xx. The serial inter-
face of the AD7827 is optimized for communication with such
devices.
The serial interface of the AD7827 uses a three-wire interface to
communicate with a Master. The serial clock pin (SCLK) is a
logic input and determines the bit transfer rate. The Receive
Frame Synchronization pin (RFS) is a logic output and used to
synchronize the data with a continuous serial clock. The data
output pin (DOUT) is a logic output and serial data is shifted
out onto this pin on the rising edge of the serial clock. The first
rising edge of the serial clock after the end of a conversion causes
the RFS pin to go logic low. (See Figure 15 below.) The DOUT pin
leaves its high impedance state and the first MSB is shifted out
on the first SCLK rising edge after the end of conversion. The
remaining seven data bits are shifted out on subsequent SCLK
rising edges. The DOUT pin enters its high impedance state again
on the falling edge of the eighth SCLK after RFS goes low. The
RFS output goes high again on the rising edge of the ninth SCLK.
If the AD7827 does not receive a ninth SCLK, the RFS will be
reset logic high by the next falling edge of
CONVST.
