** INITIAL DELAY & CUMULATIVE TOLERANCES:
"Error" Tolerance is for Programmed Delays Referenced to Initial Delay, Setting "000."
For example, the setting "111" delay of PECL3-2 is 14.0
±
0.8 ns ref. to "000," and 17.0
±
1.3 ns referenced to the input,
and the setting "111" delay of 3PECLH-2 is 14.0
±
0.8 ns ref. to "000," and 15.5
±
1.3 ns referenced to the input.
INPUT LOADING:
Input, Pin 6, internally connected to eight ECL
gate inputs terminated by Thevenin equivalent of 100 Ohms to -2V.
