Description
IXYS Integrated Circuits Division’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
provides 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 providing a low risk design
solution.

2RING Connection to telephone line Ring conductor.
4OH Driving this pin high asserts the off-hook condition. The hook switch
LED is current limited by an internal 300 resistor
5RI 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 converter of the
CYG2217. RCV uses a 2.5 volt reference signal, and therefore must be
capacitively coupled to host equipment that uses a ground reference.
15 NCNo Connection
16 VCC
Provides power to the CYG2217. Typically +5V, VCC should not exceed
20V.
17 XMIT+
Provides the analog input 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 that uses a ground reference.
18 GND Connection to host system ground.

2 Manufacturing Information
2.1 Handling and Assembly Recommendations
The CYG2217 is not hermetically sealed, and should not be exposed to any liquid-based rinsing processes. IXYS
Integrated Circuits Division recommends two (2) approaches: (1) the modem should be installed in a wave-soldering
process that uses a no-clean soldering flux that will mostly evaporate during the normal wave-soldering processes,
(2) the modem should be soldered in by hand after the rest of the card is wave-soldered.
2.2 Reflow Profile
This product has a maximum solder temperature as shown below.
