THE EXPOSED THERMAL PADDLE ON THE BOTTOM OF THE PACKAGE PROVIDES THE ANALOG GROUND FOR THE PART. THIS EXPOSED PADDLE MUST BE CONNECTED TO GROUND FOR PROPER OPERATION. 2. DNC = NO NOT CONNECT. DO NOT CONNECT TO THIS PIN. Figure 3. LFCSP Pin Configuration (Top View) Table 8. Pin Function Descriptions Pin No. Mnemonic Type Description ADC Power Supplies 8, 17 DRVDD Supply Digital Output Driver Supply (1.8 V Nominal). 3, 27, 28, 31, 32 AVDD Supply Analog Power Supply (1.8 V Nominal). 0 AGND, Exposed Paddle Ground Analog Ground. The exposed thermal paddle on the bottom of the package provides the analog ground for the part. This exposed paddle must be connected to ground for proper operation. 25 DNC Do Not Connect. Do not connect to this pin. ADC Analog 30 VIN+ Input Differential Analog Input Pin (+). 29 VIN− Input Differential Analog Input Pin (−). 26 VCM Output Common-Mode Level Bias Output for Analog Inputs. This pin should be decoupled to ground using a 0.1 μF capacitor. 1 CLK+ Input ADC Clock Input—True. 2 CLK− Input ADC Clock Input—Complement. Digital Outputs 5 OR+ Output Overrange indicator—True. 4 OR− Output Overrange indicator—Complement. 7 0/D0+ (LSB) Output DDR LVDS Output Data 0—True. The output bit on the rising edge of the data clock output (DCO) from this output is always a Logic 0 (see Figure 2). 6 0/D0− (LSB) Output DDR LVDS Output Data 0—Complement. The output bit on the rising edge of the data clock output (DCO) from this output is always a Logic 0 (see Figure 2). 10 D1+/D2+ Output DDR LVDS Output Data 1/2—True. 9 D1−/D2− Output DDR LVDS Output Data 1/2—Complement. 12 D3+/D4+ Output DDR LVDS Output Data 3/4—True. 11 D3−/D4− Output DDR LVDS Output Data 3/4—Complement. 14 D5+/D6+ Output DDR LVDS Output Data 5/6—True. 13 D5−/D6− Output DDR LVDS Output Data 5/6—Complement. 16 D7+/D8+ Output DDR LVDS Output Data 7/8—True. 15 D7−/D8− Output DDR LVDS Output Data 7/8—Complement. 19 D9+/D10+ (MSB) Output DDR LVDS Output Data 9/10—True. 18 D9−/D10− (MSB) Output DDR LVDS Output Data 9/10—Complement. 21 DCO+ Output LVDS Data Clock Output—True. 20 DCO− Output LVDS Data Clock Output—Complement.
