Description
Used to Synchronize Multiple AD9958s. Connects to the SYNC_OUT pin of the
master AD9958 device.
Used to Synchronize Multiple AD9958s. Connects to the SYNC_IN pin of the slave
AD9958 devices.
Active High Reset Pin. Asserting the MASTER_RESET pin forces the AD9958’s
internal registers to their default state, as described in the Register Map.
External Power-Down Control.
Analog Power Supply Pins (1.8 V).

Complementary DAC Output. Terminates into AVDD.
Establishes the Reference Current for all DACs. A 1.91 k resistor (nominal) is
connected from Pin 17 to AGND.
Complementary Reference Clock/Oscillator Input. When the REF_CLK is operated
in single-ended mode, this pin should be decoupled to AVDD or AGND with a
0.1 μF capacitor.
Reference Clock/Oscillator Input. When the REF_CLK is operated in single-ended
mode, this is the input. See Modes of Operation section for the reference clock
configuration.
