Description
This range of devices is designed to protect xDSL line-driver
interfaces from overvoltages. Overvoltages are normally caused
by a.c. power-system or lightning-flash disturbances which are
induced or conducted onto the telephone line. These symmetri-
cal protectors are two-terminal thyristor-crowbar devices. They
can be used to protect between conductors, or a pair of devices
can be deployed to protect from line to ground. When placed
between the xDSL line driver IC and the transformer, this
(Ring)
SD-TISP4-002-a
protector will clamp and switch into a low-impedance state, safely diverting the energy transferred by the xDSL coupling transformer.
The low capacitance design makes this device suitable for designs from ADSL all the way up to 30 MHz VDSL2.
Telecom ports need protection against Common Mode (Longitudinal) and Differential (Metallic) surges, to comply with international
standards such as ITU-T K.20, K.21 or K.45, Telcordia GR-1089-CORE and YD/T. Common Mode surges are resisted by the galvanic
isolation of the coupling transformer which is commonly rated to 2 kV or greater. Differential surges can be transmitted by the
transformer, and can stress the Line Driver Interface IC. As the xDSL interface circuit is designed to operate from 3 kHz to to 30 MHz,
nearby high frequency events - such as cable flashover or primary protection activation - can generate damaging conditions for the
interface requiring this type of protection.
