Hi, I need to make a high speed counting circuit for part of a project, Im going to be using ECL logic and the
MC10EP016 ON Semiconductor 1GHz counter, i'm a bit fuzzy on ECL logic though. They have a simple schematic of a cascaded counter here on page 10,

I know there's some odd things with ECL regarding the Vbb output, I'm unsure whether it should be grounded or connected to the differential clock input? I'm also unsure what the PE output is used for in the counter circuit, is it just constantly pulled high?
I plan on cascading three counters together, so any tips on implementing this efficiently will be great.
Thanks
