Abstract :
A highly integrated AFE chip for VDSL-4band in 0.18/spl mu/m CMOS draws 450mW from a single 1.8V supply. The 12MHz bandwidth transceiver employs an 11 b ADC, a 12b DAC, automatically tuned anti-aliasing and reconstruction filters, and programmable gain amplifiers. Beside the basic transceiver circuitry, it also provides clock generation and wake-up circuitry on a 7.5mm/sup 2/ die.
