General Description
The LMK040xx Evaluation Board simplifies evaluation of the LMK040xxB Precision Clock
Conditioner with Dual PLLs and Integrated VCO. Configuring and controlling the board is
accomplished using National Semiconductor’s CodeLoader software, which can be downloaded
from: http://www.national.com/timing/software/.
The CodeLoader software will run on a Windows 2000 or Windows XP PC. The CodeLoader
software is used to program the internal registers of the LMK040xxB device through a
MICROWIRE
