The ADSP-21mod870-110 is a complete single chip. All datapump and controller functions are implemented on a single 0.4 square-inch chip. This modem package allows the highest modem port density, while achieving the lowest power consumption in a software upgradable platform. The ADSP-21mod870-110 is designed for high density systems such as remote access servers (see Figure 1). Its high performance DSP core, large on-chip SRAM, TDM serials port and 16-bit DMA port provide efficient control and data communication with minimal chip count. The modem software provides a number of data modulations, such as V.34, 56K bps PCM, and ISDN with a software upgrade path to future standards, and new applications, such as voice over network. The host interface allows system access to modem statistics such as call progress, connect speed and modulation parameters such as retrain count and symbol rate. ON-CHIP SRAM
