AD9446
OPERATIONAL MODE SELECTION
Data Format Select
The data format select (DFS) pin of the AD9446 determines
the coding format of the output data. This pin is 3.3 V CMOS
compatible, with logic high (or AVDD1, 3.3 V) selecting twos
complement and DFS logic low (AGND) selecting offset binary
format. Table 10 summarizes the output coding.
Output Mode Select
The OUPUT MODE pin controls the logic compatibility,
as well as the pinout of the digital outputs. This pin is a CMOS-

compatible input. With OUTPUT MODE = 0 (AGND), the
AD9446 outputs are CMOS compatible, and the pin assignment
for the device is as defined in Table 8. With OUTPUT MODE = 1
(AVDD1, 3.3 V), the AD9446 outputs are LVDS compatible, and
the pin assignment for the device is as defined in Table 7.
Duty Cycle Stabilizer
The DCS circuit is controlled by the DCS MODE pin; a CMOS
logic low (AGND) on DCS MODE enables the DCS, and logic
high (AVDD1, 3.3 V) disables the controller.
