Description
Digital Inputs.
Digital I/O Supply Voltage Input (1.8 V to 3.3 V Nominal).
Digital Common.
Digital Core Supply Voltage Output (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 Input (1.8 V to 3.3 V). CVDD must be ≥ DVDD.
LVCMOS Sampling Clock Input.
Sampling Clock Supply Voltage Common.
Q DAC Output Common-Mode Level. When the internal on-chip (QR
the on-chip QR
disabled, this pin is the common-mode load for Q DAC and must be connected to AVSS through a resistor, see
the Using the Internal Termination Resistors section. Recommended value for this external resistor is 0 Ω.
Load Resistor (62.5 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 (62.5 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 Input (1.8 V to 3.3 V).
Load Resistor (62.5 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.
