Abstract

An IF-baseband multi-chip module, fabricated in 3.3V 0.35μm mixed-signal and 1.8V 0.18 μm digital CMOS provides OQPSK demodulation with carrier recovery, memory and control, voice-companding codecs, and SLIC interfaces (SIs) for a CATV telephony distribution system. The die area of the mixed-signal IC is 84.9mm² and 15.2mm² for the digital IC. The power dissipation is 660mW.
