CHOOSING AC-COUPLING CAPACITORS
The choice of ac-coupling capacitors at the input (PIN, NIN)
and output (DATAOUTP, DATAOUTN) of the ADN2819 must
be chosen such that the device works properly at the lower
OC-3 and higher OC-48 data rates. When choosing the
capacitors, the time constant formed with the two 50 resistors
in the signal path must be considered. When a large number of
consecutive identical digits (CIDs) are applied, the capacitor
voltage can drop due to baseline wander (see Figure 23), causing
pattern dependent jitter (PDJ).
Rev. B | Page 19 of 24
For the ADN2819 to work robustly at both OC-3 and OC-48, a
minimum capacitor of 1.6 μF to PIN/NIN and 0.1 μF on
DATAOUTP/DATAOUTN should be used. This is based on the
assumption that 1000 CIDs must be tolerated and that the PDJ
should be limited to 0.01 UI p-p.

3. WHENTHE BURST OF DATA STARTS AGAIN,THE DIFFERENTIAL DC OFFSET ACROSSTHE AC COUPLING CAPACITORS IS APPLIEDTOTHE INPUT LEVELS,
CAUSING A DC SHIFT INTHE DIFFERENTIAL INPUT. THIS SHIFT IS LARGE ENOUGH SUCHTHAT ONE OFTHE STATES, EITHER HIGH OR LOW DEPENDING ON
