Page 4: Introduction
This section describes the jumpers and connectors on the EVM as well and how to properly connect, set up and use the LMK00725EVM. With this EVM, one could distribute one of two input clocks to up to 5 LVPECL outputs. Therefore, a minimum of one clock source is needed and appropriate test equipment to observe or measure the outputs. -

(e.g. LVPECL), is recommended because it typically provides higher slew rate and common-mode noise rejection compared to a single-ended input (LVCMOS/LVTTL or sine-wave, for example).
