LMK Clock Design Tool

National Clock Design Tool software is used to aid part selection, loop filter design, and simulation of LMK clock conditioner timing device solutions. Enter desired output frequencies and optionally a reference frequency to find which National devices meet the specified requirements along with divider values and a recommended loop filter to minimize jitter.

CodeLoader 4.1 for LMK and LMX Devices
National's CodeLoader 4 software is used to program LMK and LMX products through either the USB or LPT port of a computer. Aside from this function, it is also provides information on how to program the part by showing the bits that are actually sent.
