THEORY OF OPERATION
The ADATE205 has two general classes of logic inputs:
differential inputs for controlling functions that generally need
to be operated at high speed, and single-ended CMOS inputs
for setting operating modes or other low speed functions. The
differential inputs have a wide common-mode range that allows
them to be used with a variety of logic families. The differential
inputs can also be used single-ended, with one input from each
pair of inputs tied to a fixed reference, but this makes precise
timing more difficult to achieve.

These differential input pins provide 50 Ω input termination
resistors for use as desired. The single-ended inputs have an
input range compatible with most logic families and are high
impedance to make driving them very easy. The switching
threshold for the single-ended inputs is preset to one-half of the
voltage at the CMOS_VDD pin.
