General Description

The LMK03002C Evaluation Board simplifies evaluation of the LMK03002C Precision Clock

Conditioner with Integrated VCO. The package consists of an evaluation board and CodeLoader

software. The CodeLoader software will run on a Windows 2000 or Windows XP PC. The purpose of

the CodeLoader software is to program the internal registers of the LMK03002C device through a

MICROWIRE

The LMK0300xC PCB works for many LMK0300xC devices. Because of this the silkscreen on

the board is different from actual clock outputs in the datasheet and in CodeLoader. Refer to the

table below for the correct mapping.
