LVDS Clock input pins for the ADC. The differential clock
signal must be a.c. coupled to these pins. The input signal is
sampled on the falling edge of CLK+. See Section 1.1.2 for a
description of acquiring the input and Section 2.3 for an
overview of the clock inputs.
Analog signal inputs to the ADC. The differential full-scale
input range is 650 mV

Common Mode Voltage. The voltage output at this pin is
required to be the common mode input voltage at V
V
when a.c. coupling is used at the analog inputs. This pin is
capable of sourcing or sinking 100µA. See Section 2.2.
Bandgap output voltage capable of 100 µA source/sink.
Calibration Running indication. This pin is at a logic high when
calibration is running.
