CodeLoader 4 for Programming LMX and LMK Device Registers
National's CodeLoader 4 software is used to program National's LMX PLLs and LMK timing devices through either the USB or LPT port of a computer. In addition, it is also provides information on how to program the part by showing the bits that are actually sent.
EasyPLL Loop Filter Design Tool & Simulation for LMX PLL/VCO Products
EasyPLL is a browser-based simulator which allows you to specify the PLL parameters, customize the loop filter, analyze the simulation results, and examine the wave forms. You can change parameters and analyze the results in order to fine tune the design.
