Notes:
1) C1, C2, FB1, and FB2 provide filtering to meet EMI restrictions. They may be omitted if your equipment meets the appropri-
ate EMI standards without them.
2) Some countries including Germany use billing tones which can interfere with communciations. L1 blocks the tone from
reaching the receiving equipment. This filter is not required for certification but is recommended for applications to be used in
Germany to prevent compromises in performance.
3) In rare instances when the CTR21 current limiting circuit is active, the XEV90C may be required to dissipate more than 2
Watts from the flow of loop current. A Heat Sink is required to dissipate the resulting heat without endangering the device.
Xecom recommends an AAVID 3352 or equivalent heat sink for applications which support CTR21.
4) UL1950 requires minimum creepage and clearance distances to be maintained for telecommunications circuits. Clearance is
the straight-line distance between two conductive points. Creepage is the distance along the surface between two conductive
points. Consult UL1950 for the minimum creepage and clearance distances which apply to your equipment.
5) By adding an switch S1 in place of J1 it is possible to have a single DAA which is software selectable for European or North
American applications.
