CLARE CYG2120 Cybergate Datasheet

CYBERGATE™
CYG2100/CYG2110/CYG2120
DESCRIPTION
Clare’s CYG21XX Series DAA modules provide a
complete telephone line interface circuit in a small
1.07" x 1.07" x 0.4" package. The modules provide a
fast and cost effective solution for designs that
require an interface to the telephone line. The
CYG2100 is designed to meet PTT and safety
regulations in 13 countries.
The CYG2110 and CYG2120 are designed to meet PTT
regulations in France and Spain, respectively.

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

I
OH
Driving this pin LOW asserts the off-hook condition. The
hookswitch LED is current limited by an internal 470Ω
resistor.
6

MUTE
Driving this pin LOW activates the mute relay for pulse
dialing. The mute control is activated on or slightly before
(tpms max.) the start of the first dial pulse, then kept active
until the end (50ms max.) of the last dial pulse. The mute
relay LED is current limited by an internal 470Ω resistor.
7
I
VCC
Provides power to the hookswitch LED. Typically +5V for
≈ 8mA LED current. LED is current limited by an internal
470Ω resistor. VCC should not exceed 20V.
