AD9780 Pin Function Descriptions Pin No. Mnemonic Description 1, 6 CVDD18 Clock Supply Voltage (1.8 V). 2, 5 CVSS Clock Supply Return. 3, 4 CLKP, CLKN Differential DAC Sampling Clock Input. 7, 28, 48 DVSS Digital Common. 8, 47 DVDD18 Digital Supply Voltage (1.8 V). 9 to 24, 31 to 38 D11P, D11N to D0P, D0N LVDS Data Inputs. D11 is the MSB, D0 is the LSB. 25, 26 DCOP, DCON Differential Data Clock Output. LVDS clock at the DAC sample rate. 27 DVDD33 Digital Input and Output Pad Ring Supply Voltage (3.3 V). 29, 30 DCIP, DCIN Differential Data Clock Input. LVDS clock aligned with input data. 39 to 46 NC No Connection. Leave these pins floating. 49 SDO Serial Port Data Output. 50 SDIO Serial Port Data Input (4-Wire Mode) or Bidirectional Serial Data Line (3-Wire Mode). 51 SCLK Serial Port Clock Input. 52 CSB Serial Port Chip Select (Active Low). 53 RESET Chip Reset (Active High). 54 FS ADJ Full-Scale Current Output Adjust. 55 REFIO Analog Reference Input/Output (1.2 V Nominal). 56, 57, 71, 72 AVDD33 Analog Supply Voltage (3.3 V). 58, 61, 64, 67, 70 AVSS Analog Common. 59 IOUT2P DAC Current Output. Full-scale current is sourced when all data bits are 1s. 60 IOUT2N Complementary DAC Current Output. Full-scale current is sourced when all data bits are 0s. 62, 63 AUX2P, AUX2N Differential Auxiliary DAC Current Output (Channel 2). 65, 66 AUX1N, AUX1P Differential Auxiliary DAC Current Output (Channel 1). 68 IOUT1N Complementary DAC Current Output. Full-scale current is sourced when all data bits are 0s. 69 IOUT1P DAC Current Output. Full-scale current is sourced when all data bits are 1s. Heat Sink Pad N/A The heat sink pad on the bottom of the package should be soldered to the PCB plane that carries AVSS. |
