Using an external word clock with Esoteric cd/sacd players

Considering the use of an external word clock with my Esoteric cd/sacd player, it has a word clock BNC input. Wanted to ask two questions;
1.) Are you relegated to using only an Esoteric word clock device? or
2.) Can you use another manufacturer like some of the pro audio word clocks, eg. Antelope OCXHD, Black Lion, Tascam, etc.?
Thanks for your input.
