AD9953
Rev. A | Page 26 of 32
There are two phases to a communication cycle with the
AD9953. Phase 1 is the instruction cycle, which is the writing of
an instruction byte into the AD9953, coincident with the first
eight SCLK rising edges. The instruction byte provides the
AD9953 serial port controller with information regarding the
data transfer cycle, which is Phase 2 of the communication cycle.
The Phase 1 instruction byte defines whether the upcoming data
transfer is read or write and the serial address of the register
being accessed.
The first eight SCLK rising edges of each communication cycle
are used to write the instruction byte into the AD9953. The
remaining SCLK edges are for Phase 2 of the communication
cycle. Phase 2 is the actual data transfer between
f bytes transferred
during Phase 2 of the communication cycle is a function of the
register being accessed. For example, when accessing the Control
Function Register No. 2, which is three bytes wide, Phase 2 requires
that three bytes be transferred. If accessing the frequency tuning
word, which is four bytes wide, Phase 2 requires that four bytes
be transferred. After transferring all data bytes per the
instruction, the communication cycle is completed.
At the completion of any communication cycle, the AD9953
serial port controller expects the next eight rising SCLK edges
to be the instruction byte of the next communication cycle. All
data input to the AD9953 is registered on the rising edge of
SCLK. All data is driven out of the AD9953 on the falling
