Description
1 to 4 DB[11:8]
Digital Inputs.
5
DVDDIO
Digital I/O Supply Voltage (1.8 V to 3.3 V Nominal).
6
DVSS
Digital Common.
7
DVDD
Digital Core Supply Voltage (1.8 V).
8 to 14 DB[7:1]
Digital Inputs.
15
DB0 (LSB)
Digital Input (LSB).
16
DCLKIO
Data Input/Output Clock. Clock used to qualify input data.
17
CVDD
Sampling Clock Supply Voltage (1.8 V to 3.3 V). CVDD must be ≥ DVDD.
18
CLKIN
LVCMOS Sampling Clock Input.
19
CVSS
Sampling Clock Supply Voltage Common.
20
CMLQ
Q DAC Output Common-Mode Level.
21
RLQN
Load Resistor (62.5 Ω) to the CMLQ Pin.
22
QOUTN
Complementary Q DAC Current Output. Full-scale current is sourced when all data bits are 0s.
23
QOUTP
Q DAC Current Output. Full-scale current is sourced when all data bits are 1s.
24
RLQP
Load Resistor (62.5 Ω) to the CMLQ Pin.
25
AVSS
Analog Common.
26
AVDD
Analog Supply Voltage (1.8 V to 3.3 V).
27
RLIP
Load Resistor (62.5 Ω) to the CMLI Pin.
28
IOUTP
Complementary I DAC Current Output. Full-scale current is sourced when all data bits are 0s.
29
IOUTN
I DAC Current Output. Full-scale current is sourced when all data bits are 1s.
30
RLIN
Load Resistor (62.5 Ω) to the CMLI Pin.
31
CMLI
I DAC Output Common-Mode Level.
32
FSADJQ/AUXQ Full-Scale Current Output Adjust for Q DAC. Connect to AVSS through a resistor.
Auxiliary Q DAC Output When Internal On-Chip, RSET, is Enabled.
33
FSADJI/AUXI Full-Scale Current Output Adjust for I DAC. Connect to AVSS through a resistor.
Auxiliary I DAC Output When Internal On-Chip, RSET, is Enabled.
34
REFIO
Reference Input/Output. Serves as a reference input when the internal reference is disabled. Provides a 1.0 V
reference output when in internal reference mode (a 0.1 μF capacitor to AVSS is required).
35
RESET/PINMD Reset. In SPI mode, pulse RESET high to reset SPI registers to default values.
Pin Mode. A constant Logic 1 puts the device into pin mode.
