Direct Digital Synthesizer IC for SDR transceiver chip with spurious performance improvement technology

Abstract

—A fundamental requirement of an SDR transceiver is signal generation and processing across all frequencies of interest. Motorola's 90 nm SDR transceiver chip implementation has achieved continuous coverage from 0.1-4 GHz with the introduction of integrated direct digital synthesis (DDS). This is based on an innovative new architecture called digital to… (More)
