The SY87729/39L are rate independent fractional-N
frequency synthesizer ICs. From a single reference source,
they can generate any clock frequency from 10MHz to
729MHz very accurately.
This document provides a detailed description of the
evaluation board, evaluation procedure and the simple
configuration software it uses. Complete information in this
