CLOCK INPUT CONSIDERATIONS
For optimum performance, the AD9211 the sample clock inputs
(CLK+ and CLK-) should be clocked with a differential signal.
This signal is typically ac-coupled into the CLK+ and CLK- pins
via a transformer or capacitors. These pins are biased internally
and require no additional bias (See Figure X).

Figure .Equivalent Clock Input Circuit
Figure X shows one preferred method for clocking the AD9211.
The clock source (low jitter) is converted from single-ended to
differential using an RF transformer. The back-to-back Schottky
diodes across the transformer secondary limit clock excursions
into the AD9211 to approximately 0.8 V p-p differential. This
helps prevent the large voltage swings of the clock from feeding
through to other portions of the AD9211 while preserving the
fast rise and fall times of the signal, which are critical to a low
jitter performance.

Figure X. Transformer Coupled Differential Clock for AD9230/AD9211
If a low jitter clock is available, another option is to ac-couple a
differential PECL signal to the sample clock input pins as shown
in Figure X. The AD9512 (or same family) from offers excellent
jitter performance.
