INTERFACING EXAMPLES
The SPI interface of the AD5360 and AD5361 is designed to
allow the parts to be easily connected to industry standard DSPs
and microcontrollers. Figure 25 shows how the AD5360/AD5361
can be connected to the Analog Devices, Inc., Blackfin DSP. The
Blackfin has an integrated SPI port that can be connected directly
to the SPI pins of the AD5360 or AD5361, and programmable
I/O pins that can be used to set or read the state of the digital
input or output pins associated with the interface.

Figure 25. Interfacing to a Blackfin DSP
The Analog Devices ADSP-21065L is a floating-point DSP with
two serial ports (SPORTs). Figure 26 shows how one SPORT
can be used to control the AD5360 or AD5361. In this example,
the transmit frame synchronization (TFS) pin is connected
to the receive frame synchronization (RFS) pin. Similarly,
the transmit and receive clocks (TCLK and RCLK) are also
connected together. The user can write to the AD5360 or
AD5361 by writing to the transmit register. A read operation
can be accomplished by first writing to the AD5360/AD5361
to tell the part that a read operation is required. A second write
operation with a NOP instruction causes the data to be read
from the AD5360/AD5361. The DSPs receive interrupt can be
used to indicate when the read operation is complete.
