PRODUCT BRIEF
Infineon's standard Packet over VDSL (PoVDSL) provides Ethernet transport over standard QAM VDSL. The chipset provides an xMII interface allowing "plug and play" connectivity for Switch/Line cards and CPE applications. VDSL is a robust, fully standardized technology. Infineon's packet based 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 PoVDSL chipset implements QAM modulation, as defined in the VDSL standards. Its spectral allocation enables coexistence with voice and ISDN services on the same line, and with other xDSL technologies in the same bundle. Packet over VDSL provides fully integrated copper access technology with high resolution video, high-speed Internet and advanced telephony services over a single twisted pair. Features s Ethernet packet transmission over standard VDSL s FTTC/Cab and broadband extension over copper wire s Quadrature Amplitude Modulation (QAM) s Frequency Division Duplexing (FDD) s 4, 3 or 2 - band operation s High speed VDSL PHY applications according to ANSI, ETSI and ITU-T specifications s Transmission of packets over VDSL using standard PTM-TC according to the ITU-T G993.1 VDSL Standard s Dual latency support with built-in interleaver memory s IEEE 1149.1 JTAG test access port s Power Backoff s Embedded AGC controller s Embedded interleaver SRAM s Backward compatibility with the Infineon 2-band 10BaseS chipset
