*Unless otherwise specified, dynamic measurements are made with
all outputs terminated into 50 Ω .
|
Notes:
(1). The output rise and fall times are measured with both the Q and
Q outputs terminated into 50 Ω. If an unused
complementary output is left unterminated, slight increase in rise and fall
times will result.
(2). fMAX is measured by connecting its inputs to the
PRL450ND, ECL to TTL
Logic Level Translator, and its outputs to the PRL-350ECL comparator. The input
threshold voltage of the PRL-350ECL is set to 2 V. The outputs of the PRL-350ECL
are divided by two using the PRL-255. The outputs of the PRL 255 are then
measured using the PRL-550NQ4X, four channel ECL
Terminator, connected to a 50 Ω
input sampling 'scope.
