Just wire it up and give it a try. The PPS output is a good solid TTL signal. It will work fine unless you are going very long distances. Their data sheet says it will drive 50 ohms. If you have a scope handy, see what it looks like. Without a 50 ohm terminater, it is likely to be 2x the TTL level. Who knows what "TTL" means these days. It's probably CMOS, either from 5V or from 3.3V. -- These are my opinions, not necessarily my employer's.
