SERIAL INTERFACE TIMING
All of the internal registers of the AD9991 are accessed through
a 3-wire serial interface. Each register consists of an 8-bit address
and a 24-bit data-word. Both the 8-bit address and 24-bit data-
word are written starting with the LSB. To write to each register,
a 32-bit operation is required, as shown in Figure 40a. Although
many registers are fewer than 24 bits wide, all 24 bits must be
written for each register. For example, if the register is only 10
bits wide, the upper 14 bits are don’t cares and may be lled with
0s during the serial write operation. If fewer than 24 bits are writ-
ten, the register will not be updated with new data.

NOTES
1. SDATA BITS ARE LATCHED ON SCK RISING EDGES. SCK MAY IDLE HIGH OR LOW IN BETWEEN WRITE OPERATIONS.
2. ALL 32 BITS MUST BE WRITTEN: 8 BITS FOR ADDRESS AND 24 BITS FOR DATA.
3. IF THE REGISTER LENGTH IS <24 BITS, “DON’T CARE” BITS MUST BE USED TO COMPLETE THE 24-BIT DATA LENGTH.
4. NEW DATA VALUES ARE UPDATED IN THE SPECIFIED REGISTER LOCATION AT DIFFERENT TIMES, DEPENDING ON THE
PARTICULAR REGISTER WRITTEN TO. SEE THE REGISTER UPDATES SECTION FOR MORE INFORMATION.

NOTES
1. MULTIPLE SEQUENTIAL REGISTERS MAY BE LOADED CONTINUOUSLY.
2. THE FIRST (LOWEST ADDRESS) REGISTER ADDRESS IS WRITTEN, FOLLOWED BY MULTIPLE 24-BIT DATA-WORDS.
3. THE ADDRESS WILL AUTOMATICALLY INCREMENT WITH EACH 24-BIT DATA-WORD (ALL 24 BITS MUST BE WRITTEN).
4. SL IS HELD LOW UNTIL THE LAST DESIRED REGISTER HAS BEEN LOADED.

Figure 40b. Continuous Serial Write Operation
Figure 40b shows a more efcient way to write to the registers,
using the AD9991’s address auto-increment capability. Using
this method, the lowest desired address is written rst, followed
by multiple 24-bit data-words. Each new 24-bit data-word will
automatically be written to the next highest register address. By
eliminating the need to write each 8-bit address, faster register
loading is achieved. Continuous write operations may be used
starting with any register location, and may be used to write to as
few as two registers, or as many as the entire register space.
