CYBERGATE™

Features

Description

• Low distortion transformer signal coupling

Clare’s Cybergate™ CYG2217 DAA module provides a

complete telephone line interface circuit, including a 2-4

wire converter for transmit and receive signal separation

in a small 1.07" x 1.07" x 0.4" package. The module pro-

vides a fast and cost effective solution for designs that

require an interface to the telephone line. The module is

designed to meet FCC part 68 requirements thus provid-

ing a low risk design solution.

Handling and Assembly Recommendations

The CYG2217 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.

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 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.

TIP

RING

RING Connection to telephone line Ring conductor.

Driving this pin high asserts the off-hook condition. The

hookswitch LED is current limited by an internal 300Ω resis-

tor.

Active LOW indicates an incoming ring signal. This is pulsed

LOW by the AC ring signal and is not a steady state LOW

during ringing.

14 RCV Provides the analog output signal from the 2-4 wire convert-

er of the CYG2217. RCV uses a 2.5 volt reference signal and

therefore must be capacitively coupled to host equipment

which uses a ground reference.

No connection.

V_CC

Provides power to the CYG2217. Typically +5V, V_CCshould

not exceed 20V.

17 XMIT+ Provides the analog intput signal from the 2-4 wire converter

of the CYG2217. XMIT+ uses a 2.5 volt reference signal and

therefore must be capacitively coupled to host equipment

which uses a ground reference.

18 GND Connection to host system ground.
