Lucent Technologies Inc.
Electrical Characteristics
Bit rate = 2.488 Mbits/s NRZ and data pattern = 2
23
– 1 PRBS, unless otherwise indicated. See Figure 3 for the tim-
ing and signal levels and Figure 5 for the test circuit, when using the TF1001A test fixture.
Note:
Minimum and maximum values are testing requirements. Typical values are characteristics of the device
and are the result of engineering evaluations. Typical values are for information purposes only and are not
part of the testing requirements.
