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.

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.
