Description
Summary:A 28 nm CMOS software-defined transceiver (SDTRX) enabling high-speed data (HSD) streaming, including ultra HD TV, within home cable networks is presented. By making efficient use of available cable bandwidth, the SDTRX dynamically handles up to 1024-QAM OFDM-modulated HSD streams. This paper addresses SDTRX system-level design methodology as the key driver in enabling performance optimization for achieving a wide frequency range of operation at lowest power and area consumption. By employing an optimized architecture constructed on available state-of-the-art 28 nm functional building blocks, the monolithic SDTRX consists of a mixer-based harmonic rejection RX with a digital-to-analog converter-based TX and a smart phase-locked loop system. It operates over 0.4-1.7 GHz frequency range while consuming less than 475 mW in half-duplex mode. Moreover, by developing a simple transmitter (TX) to receiver (RX) loopback circuit, the system is enabled to efficiently calibrate TX output power and to remove the need for a dedicated external pin. This low-cost SDTRX is embedded in various 28 nm CMOS multimedia system-on-chip and is, to the authors' knowledge, the first reported transceiver front-end to enable true HSD streaming within home cable networks.
