CYG23XX

DS-CPC2300-R1

Clare’s CybergateTM23XX DAA modules provide a com­plete telephone line interface circuit in a small 1.07" x

1.07" x 0.4" package. This module provides a fast and
cost effective solution for designs that require an interface
to the telephone line. The CYG23XX0 is designed to
meet PTT and safety regulations in Germany.

Handling and Assembly Recommendations

The CYG23XX products are not hermetically sealed and should not be exposed to any liquid-based rinsing processes. Clare recommends two (2) approaches. The
modem should either use a no clean soldering flux that would mostly evaporate during the normal wave soldering processes, or be soldered in by hand after the rest
of the card is wave soldered.

Electrical Characteristics

Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at these or
any other conditions beyond those indicated in the opera­tional sections of this data sheet is not implied. Exposure
of the device to the absolute maximum ratings for an
extended period may degrade the device and effect its
reliability.
