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.

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.

Transformer isolated audio signal coupling path for the telephone line. When system is off-hook (OH driven LOW) LOOPI is driven LOW continuously on CYG2010/2011/2030/2031 devices. Keying pin for CYG2000/CYG2001, do not use. Driving this pin LOW asserts the off-hook condition. The hookswitch LED is current limited by an internal 470 resistor. Active LOW indicates an incoming ring signal. This is pulsed LOW by the AC ring signal at the ring frequency from 15-40Hz. Connection to telephone line Ring conductor. Connection to telephone line Tip conductor. Caller ID connection on CYG2020/2021/2030/2031. CID1/CID2 connect to an external 1-Form-A solid state relay (CP Clare LCA110). When the SSR is closed (connecting CID1 to CID2) Caller ID information is presented to LINE1/LINE2 after the first telephone ring burst. Caller ID connection. See CID2 above. Connected to host system ground. Provides power to the hookswitch LED. Typically +5V for 8mA LED current. LED is current limited by an internal 470 resistor. VCC should not exceed 20V. 14 17 18 O I I CID1 GND VCC 4 www.clare.com Rev. 1 CYG20XX Typical Application CYG2000/CYG2001 +5V 294 TX1 18 VCC 10 GYRATOR SURGE PROTECTOR LINE 1 1 VCC RING HYBRID CIRCUIT TX2 LINE 2 2 HOOKSWITCH VCC RING DETECT NETWORK TO TELEPHONE LINE RX OH RELAY GND RING OH RING 8 9 470 56k VCC 11 17 GND TIP Rev. 1 www.clare.com 5 Worldwide Sales Offices CLARE LOCATIONS Clare Headquarters 78 Cherry Hill Drive Beverly, MA 01915 Tel: 1-978-524-6700 Fax: 1-978-524-4900 Toll Free: 1-800-27-CLARE Clare Micronix Division 145 Columbia Aliso Viejo, CA 92656-1490 Tel: 1-949-831-4622 Fax: 1-949-831-4628 EUROPE European Headquarters CP Clare nv Bampslaan 17 B-3500 Hasselt (Belgium) Tel: 32-11-300868 Fax: 32-11-300890 France Clare France Sales Lead Rep 99 route de Versailles 91160 Champlan France Tel: 33 1 69 79 93 50 Fax: 33 1 69 79 93 59 Germany Clare Germany Sales ActiveComp Electronic GmbH Mitterstrasse 12 85077 Manching Germany Tel: 49 8459 3214 10 Fax: 49 8459 3214 29 Italy C.L.A.R.E.s.a.s.
