Abstract

The satellite communications are expected to play an important role to provide broadband multimedia services in the 21st century. According to this requirements, this paper describes the design and implementation of ATM-based high speed satellite modem ASIC chipset. The ASIC chip consists of three main parts, CODEC, Modulator and Demodulator. It supports burst and continuous mode operation with TDMA frame consisted of Reference bursts, Inbound burst, and Traffic burst. The maximum transmission rate is OC-3 (155Mbps) and the maximum operating clock speed is 220MHz. This ASIC chip was implemented with 0.25um CMOS technology.
