[time-nuts] HP Z3801A - How to convert the 1PPS & 10MHz Differential Pseudo ECL Output?

2006-04-09 Thread Don Mimlitch
I have a HP Z3801A which outputs the 1 PPS and 10MHz as Differential Pseudo ECL. What is this? How do I access these signals? How do I convert them to TTL or CMOS Levels. Are there any IC's (DIP Package) to do the conversion? For short cable runs (2 or 3 Ft.) is there a simple circuit fo
