Description
Digital Output Driver Supply (1.8 V Nominal).
Analog Power Supply (1.8 V Nominal).
Do Not Connect. Do not connect to this pin.
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.
Differential Analog Input Pin (+) for Channel A.
Differential Analog Input Pin (−) for Channel A.
Differential Analog Input Pin (+) for Channel B.
Differential Analog Input Pin (−) for Channel B.
Common-Mode Level Bias Output for Analog Inputs. This pin
should be decoupled to ground using a 0.1 μF capacitor.
ADC Clock Input—True.
ADC Clock Input—Complement.
Channel A Fast Detect Indicator (CMOS Levels).
Channel B Fast Detect Indicator (CMOS Levels).
Digital Synchronization Pin. Slave mode only.
Channel A/Channel B LVDS Output Data 0—True.
Channel A/Channel B LVDS Output Data 0—Complement.
Channel A/Channel B LVDS Output Data 1—True.
Channel A/Channel B LVDS Output Data 1—Complement.
