Cybergate
DS-CYG2911-R1
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.

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.
