U1801L TISP4G024L1W G.Fast VDSL Protector General Information This device is designed to protect ADSL, VDSL and G.Fast line driver interfaces from overvoltages up to rated limits. Overvoltages are normally caused by a.c. power-system or lightning-flash disturbances which are induced or conducted onto the telephone line. I/O 1 This protector offers protection of both lines of the twisted wire pair in a single device. When placed between the x DSL line driver IC and the transformer, this protector will clamp and switch into a low-impedance state, safely diverting the current transferred by REF the x DSL coupling transformer. The biased low capacitance design makes this device suitable for designs from ADSL to 30MHz VDSL2 to G.Fast. OBSOLETE Tele ports need protection against longitudinal and transverse surges, to ply I/O 2 REF with international standards such as ITU-T K.20, K.21 or K.45, Telcordia GR-1089-CORE and YD/T. Longitudinal surges are resisted by the galvanic isolation of the coupling transformer which is monly rated to 2 k V or greater. Transverse surges can be transmitted by the transformer, and can stress the Line Driver Interface IC. As the x DSL interface circuit is designed to operate from 3 k Hz to 106 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.
