GPSDO related questions

I’m about to add a GPSDO to improve the stability of my transverters. While my 6500 is not the primary reason I’m adding a GPSDO, it will likely get connected to it. I’m thinking of buying the BG7TBL unit which I’ve discovered comes in a few variations. Got a few questions –

1.       Does the 6500 require a sine or square wave 10 mhz signal from the GPSDO?

2.       What is the recommended input level for the 6500’s external 10 mhz input?

3.       Has anyone who is using the BG5TBL GPSDO had any problems?

The external reference clock input is used to synchronize the radio’s master oscillator.
Requires a 1.0v p-p minimum to 3.3v p-p maximum (4dBm min - +15dBm max), sine or
square wave signal.
