OUTPUT COMPLIANCE
Figure 40 is a graphical depiction of the single-ended waveform
at the output of the AD8153. The common-mode level (V
and the amplitude (V
output tail current (I
(V
dc-coupling is used. Keep in mind that the output tail current
varies with the pre-emphasis level. The user must ensure that
the high (V
within the single-ended absolute voltage range limits as
specified in Table 1. Failure to understand the implications of
output signal levels and the choice of ac- or dc-coupling may
lead to transistor saturation and poor transmitter performance.
