PEF22815 - Infineon Technologies

PRODUCT BRIEF

Never stop thinking.

Infineon’s standard 4-band VDSL (4bVDSL) is a

highly integrated chipset designed for VDSL

DSLAM/Line cards and CPE applications.

VDSL is a robust, fully standardized technology.

Infineon’s 4-band VDSL system solution delivers

transmission speeds exceeding 65 Mbit/s1). It also

provides symmetric 16 Mbit/s or asymmetric

26/3 Mbit/s broadband services at a distance of up

to 5000 ft (1500 m) over existing copper wires.

Higher rates are possible with reduced ranges.

Infineon’s ATM VDSL chipset implements QAM

modulation, as defined in the VDSL standards. Its

spectral allocation enables coexistence with voice

and ISDN services on the same line, as well as

with other xDSL technologies in the same bundle.

VDSL is an excellent way to speed up broadband

services for residential, business and commercial

environments. A typical VDSL application is the

“Last Mile Network” that offers high resolution

video, high-speed Internet and advanced tele-

phony services over a single twisted pair.
