CYG2911
Cybergate™
Description
Features
• Transformer signal coupling
• Complete ring detector circuit
• Low power hookswitch
• Electronic inductor/gyrator circuit
• Surge protection
• Caller ID pinout to external relay (optional)
• Transient protection zeners
• V.32 compatible
The CYG2911 is a Data Access Arrangement (DAA) mod-
ule providing a complete telephone line interface circuit in
a small 1.07" x 1.07" x 0.4" plastic package. This module
incorporates a circuit which signals HIGH when another
phone in parallel has been taken off-hook when the
CYG2911 is off-hook. This feature is important for cable
TV set-top boxes and direct broadcast satellite units
which must hang-up (go on-hook) when a consumer
needs the phone line to place a 911 or emergency call.
The module is designed to meet FCC Part 68 require-
ments thus providing a low-risk design solution.
• FCC Compatible
• PC board mountable
• Parallel telephone off-hook detection

Handling and Assembly Recommendations
The CYG2911 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 (@ 25˚ C)
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.

911 Signals HIGH for 20-60ms when the CYG2911 is off-hook
and another phone goes off-hook. Glitches may appear on
this pin when the CYG2911 first goes off-hook, and should
be ignored for a minimum of 200ms.

OH Driving this pin LOW asserts the off-hook condition. The
hookswitch LED is current limited by an internal 470Ω
resistor.
O
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. CID1/CID2 connect to an external 1-

closed (connecting CID1 to CID2), Caller ID information is
presented to LINE1/LINE2 after the first telephone ring
burst.
