THE HEAT SINK PAD IS CONNECTED TO AVSS AND SHOULD BE SOLDERED TO THE GROUND PLANE. EXPOSED METAL AT PACKAGE CORNERS IS CONNECTED TO THIS PAD. Figure 2. AD9717 Pin Configuration Table 7. AD9717 Pin Function Descriptions Pin No. Mnemonic 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). Provides a 1.8 V output when the internal LDO regulator is enabled. 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 (500 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 (500 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 (500 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 (500 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. The pin becomes the output of an optional, serial port driven, auxiliary DAC when the 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. The pin becomes the output of an optional, serial port driven, auxiliary DAC when the 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). |
