CYG2217
CYBERGATETM
Features * Low distortion transformer signal coupling (0.01% max) * Complete ring detector circuit * Low power hookswitch * Electronic inductor/gyrator circuit * Solid state surge protection * Transient protection zeners * Complete hybrid circuit (2-4 wire converter) included * Compatible with all modem chip sets * V.32 bis/V.34 compatible
Description Clare's CybergateTM 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.
Applications * Modems * Fax machines * Remote data acquisition * Security systems * Voice mail systems * PC motherboard * Computer telephony * Process control * Medical * PBX * Direct broadcast satellite
Approvals * UL recognized file #: E174201

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 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.

Connection to telephone line Tip connected through an external fuse. Connection to telephone line Ring conductor. Driving this pin high asserts the off-hook condition. The hookswitch LED is current limited by an internal 300 resistor. 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. 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 which uses a ground reference. No connection. Provides power to the CYG2217. Typically +5V, VCC should not exceed 20V. 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. Connection to host system ground.
