A single-chip digital cable tuner with an active splitter for cable data modems and set-top boxes is realized in a 0.5/spl mu/m, 30GHz BiCMOS technology. The IC employs a single down-conversion, low-IF architecture and can receive signals in the 48-860MHz range. Fully integrated selectivity is obtained in combination with a channel decoder. Power consumption is 1.5W with a 3.3V supply.
