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 interface.

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.

Read first, Basic Operation

Read the document,

“Installing CodeLoader 4 & USB Driver”

for instructions to prepare the computer

for usage with the evaluation board before continuing with the hardware setup.

For basic operation…

1. Connect a low noise

3.3 V

power supply to the

Vcc

connector located at the top left of the

board

2. Connect the CodeLoader cable to the

uWire

header located in the lower left.

3. Connect…

•

PC directly to the evaluation board with the LPT to uWire cable, plugging the cable

into an LPT port on the computer and then the 10 pin ribbon connector to the

evaluation board. This setup is shown below.

The cable can be removed after

programming to minimize noise and EMI.

•

Available separately, the USB <--> uWire board to the PC with the USB cable and the

USB <--> uWire board to the evaluation board with the 10 pin ribbon cable.
