System Timing Requirements
Figure 17 shows the relationship between the analog
inputs, input clock, frame-alignment output, serial-clock
output, and serial-data outputs. The differential ADC
input signal is sampled on the rising edge of the applied
clock signal (CLKIN+, CLKIN-), and the resulting data
appears at the digital outputs 10.5 clock cycles later.
Figure 18 provides a detailed, two-conversion timing
diagram of the relationship between inputs and outputs.
