A novel baseband digital signal processor IC for HINOC

摘要

A novel high-performance baseband digital signal processor IC for High Performance Network Over Coax (HINOC) is implemented in this paper. The design has been fabricated with SMIC CMOS 0.13um 1P8M technology. The chip die size is 10.5 mm × 10.5 mm, in which HIPHY (HINOC Physical layer) transceiver and HIMAC (HINOC Media Access Control layer) acceleration coprocessor are integrated. Using a channel bandwidth of 16 MHz, the peak Ethernet data throughput is 76 Mbps for downstream or upstream within 36 dB link attenuation. No evident performance degradation is found when handling the short Ethernet packets compared with the long ones.
