Description
IXYS Integrated Circuits Division's CYG2110 DAA
Module, designed for use in France, provides a
complete telephone line interface circuit in a small
(1.07" x 1.07" x 0.4") package. The module provides a
fast and cost-effective solution for designs that require
an interface to the telephone line.
The CYG2110 is designed to meet PTT and safety
regulations in France. Select the CYG2100 for use in
most other EU nations, except Spain.
Approvals
• EN/IEC 60950 Compliant

1.1 Absolute Maximum Ratings @ 25°C
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 conditions
beyond those indicated in the operational sections of this
data sheet is not implied.

CC
Provides power to the hook switch LED. Voltage is usually +5V
(for 8mA LED current), but can be higher if an external resistor
is placed in series with the internal 470 resistor.
