Overview

The Intel® MD563X-HaM V.90 chipset is a leap forward in technology, performance, and cost savings. This Host Accelerated Modem (HaM) solution combines and optimizes the best features from software and hardware modems. It delivers superior performance and is cost competitive with software modems.

The MD563X-HaM uses the host computer's CPU to replace the modem's controller, and it does so with minimal degradation in CPU performance. Since today's CPUs are well equipped to handle Digital Signal Processing (DSP), some of these functions are diverted to the CPU for processing. Maximum system and modem performance is maintained by splitting the processing optimally between the CPU and DSP.

Unlike software modems, there is no performance penalty because the CPU does not handle all of the controller and DSP functions. Instead, functions have been strategically optimized for accelerated performance by either the CPU or the DSP depending on which device can perform them most efficiently—delivering a price, performance ratio that is hard to match.

Optimizing CPU usage in this manner eliminates the need for a controller and reduces the size of the DSP, thereby reducing part count, board size, and the amount of silicon used. These cost saving advantages make the MD563X-HaM a high-performance and feature-rich alternative to software modems.

With an integrated PCI interface, this V.90 solution provides robust data, fax, voice, and speakerphone features. Effective data receive rates up to 56K (53.333 kbps FCC max.) ensure interoperability with major Internet service providers around the world. The MD563X-HaM is Microsoft* WHQL certified, meets Microsoft PC 98 specifications for Windows*, and is TAPI and PCI 2.2 compliant. It supports legacy applications, PC-based communication requirements, and AT commands for data, Class 1 fax and IS-101 voice.
