Handling and Assembly Recommendations
The CYG20XX 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.

LOOPI
When system is off-hook (OH driven LOW) LOOPI is driven LOW continuously
on CYG2010/2011/2030/2031 devices.
N/C
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 470Ω resistor.
9

RING
Active LOW indicates an incoming ring signal. This is pulsed LOW by the AC
ring signal at the ring frequency from 15-40Hz.

CID2
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.
