GENERAL DESCRIPTION
This user guide applies to the evaluation boards for the AD9547
and AD9548, although only the AD9548 is discussed within.
The two devices differ primarily in the number of inputs and
outputs. The only other difference is the maximum size of the
feedback divider. The AD9548 accepts input reference
frequencies as low as 1 Hz. The minimum input reference
frequency of the AD9547 is 1 kHz.
The AD9548 is a very low noise DDS-based digital PLL clock
synthesizer with up to eight reference inputs and up to eight
outputs. The AD9548 features reference clock validation,
automatic holdover, and hitless reference clock switching. The
AD9548 is also capable of accepting a 1 pulse per second (pps)
reference input clock.
The AD9548 Revision E evaluation board is a compact, easy-to-
use platform for evaluating all features of the AD9548.
