Ultra-Fast ECL-Output Comparator

_______________________________________________________________________________________
The timing diagram (Figure 3) illustrates the series of
events that complete the compare function, under
worst-case conditions.
The top line of the diagram illustrates two latch-enable
pulses. Each pulse is high for the compare function
and low for the latch function. The first pulse demon-
strates the compare function; part of the input action
takes place during the compare mode. The second
pulse demonstrates a compare-function interval during
which there is no change in the input.
The leading edge of the input signal (illustrated as a
large-amplitude, small-overdrive pulse) switches the
comparator after time interval t
pd
. Output Q and Q
transistors are similar in timing. The input signal must
occur at time t
s
before the latch falling edge, and it
must be maintained for time t
h
after the edge to be
acquired. After t
h
, the output is no longer affected by
the input status until the latch is again strobed. A mini-
mum latch pulse width of t
pw
(E) is needed for the
strobe operation, and the output transitions occur after
a time t
pd
(E).
