PH(1:0)
Input
Phase Offset Bits. The phase of the output is shifted. If not used, these pins should be grounded.
00 – 0 degrees reference
01 – 90 degrees shift
10 – 180 degrees shift
11 – 270 degrees shift
4
ENOFR
Input
Enable Offset Frequency. Active High. When high, the offset frequency bus is enabled to the
phase accumulator. When low, the offset frequency bus is zeroed. This pin does not affect the
contents of the offset frequency registers. If not used, the pin should be grounded.
10
COMPOUT
Output
Comparator Output.
11
REFLO
Input
Connect to analog ground to enable the DAC’s internal 1.2V reference or connect to AV
DD
to
disable the internal reference.
12
REFIO
Input
Reference voltage input for the DAC if internal reference is disabled. Recommend the use of a
0.1
μ
F cap to ground from the REFIO pin when a DC reference voltage is used.
13
FSADJ
Full Scale Current Adjust for the DAC. Use a resistor to ground (R
SET
) to adjust the full scale
output current. Full Scale Output Current = 32 x V
FSADJ
/R
SET
, where V
FSADJ
equals the
reference voltage.
14
COMP1
Noise reduction for the DAC. Connect a 0.1
μ
F cap to AV
DD
plane.
19
COMP2
Noise reduction for the DAC. Connect a 0.1
μ
F cap to AGND plane.
18
IOUTA
Output
DAC Current Output.
17
IOUTB
Output
DAC Complementary Current Output.
20
AV
DD
Power
Analog Supply Voltage.
15, 16, 21, 24
AGND
Gnd
Analog Ground.
7, 26, 31, 43
DV
DD
Power
Digital Supply Voltage.
5, 25, 28, 29, 41
DGND
Gnd
Digital Ground.
22, 23
IN+, IN-
Input
Comparator Inputs. To power down the comparator, connect both of these pins to the analog
power supply. This will conserve ~4mA of current.
39
NC
NC
No Connect.
