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

conguration software it uses. Complete information in this

document includes:

1. Test setup and measuring frequency output with

a signal generator.

2. Test setup and measuring jitter with an internal

reference oscillator.

3. Download and use of the conguration software

4. Board schematic and Bill of Materials.
