Description
Digital Inputs.
Digital I/O Supply Voltage (1.8 V to 3.3 V Nominal).
Digital Common.
Digital Core Supply Voltage (1.8 V). Strap DVDD to DVDDIO at 1.8 V. If DVDDIO > 1.8 V, bypass DVDD with a
1.0 μF capacitor; however, do not otherwise connect it. The LDO should not drive external loads.
Digital Inputs.
Digital Input (LSB).
No Connect. These pins are not connected to the chip.
Data Input/Output Clock. Clock used to qualify input data.
Sampling Clock Supply Voltage (1.8 V to 3.3 V). CVDD must be ≥ DVDD.
LVCMOS Sampling Clock Input.
Sampling Clock Supply Voltage Common.

resistor is 0 Ω.
Load Resistor (500 Ω) to the CMLQ Pin. For the internal load resistor to be used, this pin should be tied to
QOUTN externally.
Complementary Q DAC Current Output. Full-scale current is sourced when all data bits are 0s.
Q DAC Current Output. Full-scale current is sourced when all data bits are 1s.
Load Resistor (500 Ω) to the CMLQ Pin. For the internal load resistor to be used, this pin should be tied to
QOUTP externally.
Analog Common.
Analog Supply Voltage (1.8 V to 3.3 V).
Load Resistor (500 Ω) to the CMLI Pin. For the internal load resistor to be used, this pin should be tied to
IOUTP externally.
I DAC Current Output. Full-scale current is sourced when all data bits are 1s.
Complementary I DAC Current Output. Full-scale current is sourced when all data bits are 0s.
