An integrated analog front-end for VDSL

Digital subscriber loop (DSL) technology allows high-speed transmission between the telephone central office and subscriber premises using existing unshielded twisted-pair loop plant, coexisting with telephony. Very-high-speed DSL (VDSL) is a new service aimed at loop lengths up to 3000 m, providing...

Summary:Digital subscriber loop (DSL) technology allows high-speed transmission between the telephone central office and subscriber premises using existing unshielded twisted-pair loop plant, coexisting with telephony. Very-high-speed DSL (VDSL) is a new service aimed at loop lengths up to 3000 m, providing 2-52 Mb/s data. The VDSL signal occupies the 0.2-11 MHz spectrum. This IC provides the analog functions required in a VDSL modem that uses synchronized discrete multi-tone (SDMT) line code. It is implemented in 0.35 /spl mu/m CMOS double-poly-triple-metal process and consumes 550 mW at 22.08 MHz sample rate with a single 3.3 V supply. The die measures 180/spl times/150 mil/sup 2/.
