(1) Measured with Equalizer enabled, 12db cable attenua-
tion, VDD = 5V and TA = 25°C
(2) Measured at nominal STSX-1 level with Equalizer en-
abled, VDD = 5V and TA = 25°C
Figure 5 presents the test circuit that was used to test
and measure the pulse amplitudes as listed in the
ELECTRICAL CHARACTERISTICS tables.
Figure 6, Figure 7 and Figure 8 present the Pulse
Template requirements for the E3, DS3 and STS-1
Rates.
