This is pulsed LOW by the AC ring signal, and is not a steady state LOW during ringing. 14 RCV 15 NC No Connection 16 VCC Provides power to the CYG2218. Typically +5V, VCC should not exceed 20V. 17 XMIT+ Provides the analog input signal from the 2-4 wire converter of the CYG2218. 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 telephone line Tip connected through an external fuse. Connection to telephone line Ring conductor. Provides the analog output signal from the 2-4 wire converter of the CYG2218. RCV uses a 2.5 volt reference signal, and therefore must be capacitively coupled to host equipment that uses a ground reference.

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.
