AD9913
Data Read Operation
A typical read operation follows the steps shown in Figure 33.
1.
The user supplies PCLK, CS, R/W, and the parallel address
of the register using the address pins (ADR0 through
ADR7) for the read operation.
2.
CS, R/W, and the address lines must meet the setup and
hold times relative to the 1
st
PCLK rising edge.
3.
The user releases the bus to read.
4.
The AD9913 drives data onto the bus after the second
PCLK rising edge.
5.
CS must meet the set up and hold times to the 3
rd
PCLK
rising edge.

Data Write Operation
Write operations work in a similar fashion as read operations
except that the user drives the bus for both PCLK cycles. A
typical write access follows the steps shown in Figure 34.
1.
The user supplies the PCLK, CS, R/W, and the parallel
address of the register and using the address pins
(ADR0/D0 through ADR7/D7).
2.
CS, R/W, and the address lines must meet the set up and
hold times relative to the 1
st
PCLK rising edge.
3.
Data lines must meet the set up and hold times relative to
the 2
nd
PCLK rising edge.
4.
CS must meet the set up and hold times relative to the 3
rd
PCK rising edge.
