OPERATIONS
The Intel® MD566X is an enhancement of the
MD565X chipset. Due to advancements in
architecture the DSP no longer requires 64K
of external SRAM. This new technology
improves performance while decreasing board
size, power consumption, and cost.
The MD566X owes its capabilities to the
sophisticated architecture of its controller and
DSP. Each components highly integrated
design minimizes part count and board area.
This high performance V.90 solution delivers
robust data, fax, and voice featuresincluding
full-duplex speakerphone. The single-platform
design means that no additional circuitry is
needed to support ISA, Serial, or PCMCIA
interfaces and a host of features.
The MD566X meets PC-based commun-
ications requirements for internal, external, and
PCMCIA applications. It meets Microsoft
*
PC
98 specifications for Windows
*
and legacy
applications. It also supports AT commands
for data, Voice IS-101, and Fax Class 1.
The MD566X serves multiple levels of product,
from basic feature sets to full-featured
speakerphone applications. With its powerful
controller and DSP the MD566X offers
excellent performance for todays most
demanding applications.
