PEF22810 Datasheet, PDF (1/2 Pages) Infineon Technologies AG – ETHERNET OVER VDSL CHIPSET

PRODUCT BRIEF
10BaseS^TM is an innovative technology offering the
simplicity of Ethernet coupled with the high perfor-
mance of VDSL. Utilizing 10BaseS, a system deliv-
ers 10 Mbit/s, full duplex Ethernet over existing
copper wire infrastructure up to a distance of
4000 ft/1200 m. It simultaneously supports high
speed DATA transmission with POTS, ISDN or PBX
signaling, without disruption.
Ethernet MAC and PHY functionality are integrated
into Infineon’s 10BaseS chipset, achieving direct
connectivity with standard Ethernet physical layer
and switching devices. Its VDSL technology uses
frequency division duplexing and QAM modula-
tion to provide robust operation. Its spectral allo-
cation allows noise-free coexistence with other
xDSL technologies in the same bundle.
10BaseS is the best solution for distribution of
broadband services in MDU/MTU and hospitality
markets and the most suitable solution for broad-
band LAN extension applications.
