Functional Description
3.3.2
DC Offset Compensation
The M02050-15 contains an internal DC autozero circuit that can remove the effect of DC offsets without using
external components. This circuit is configured such that the feedback is effective only at frequencies well below
the lowest frequency of interest. The low frequency cut off is typically 25 kHz.
3.3.3
PECL Outputs
The M02050-15 features 100k/300k PECL compliant outputs as shown in Figure 3-3. The outputs may be termi-
nated using any standard AC or DC-coupling PECL termination technique. AC-coupling is used in applications
where the average DC content of the data is zero e.g. SONET. The advantage of this approach is lower power con-
sumption, no susceptibility to DC drive and compatibility with non-PECL interfaces.
