DM562P
V.90 Integrated Data/ Fax/Voice/Speakerphone
Modem Device Single Chip with Memory Built in
General Description
The DM562P integrated modem is a two-chipset
design that provides a complete solution for
state-of-the-art, voice-band Plain Old Telephone
Switching (POTS) communication. The modem
provides for Data (up to 56,000bps), Fax (up to
33,600bps), Voice and Full Duplex Speaker-phone
functions to comply with various international
standards.
The design of the DM562P is optimized for desktop
personal computer applications, embedded
microprocessor applications and Multi-Function
Peripheral (MFP) FAX application. It provides a low
cost, highly reliable, maximum integration, with the
minimum amount of support required. The DM562P
modem can operate over a dial-up network (PSTN)
or 2 wire leased lines.
The modem integrates auto dial and answer
capabilities, asynchronous data transmissions,
serial and parallel interfaces, various tone detection
schemes and data test modes.
The DM562P modem reference design is
pre-approved for FCC part 68 and provides
minimum design cycle time, with minimum cost to
insure the maximum amount of success.
The simplified modem system, shown in figure
below, illustrates the basic interconnection between
the MCU, DSP, AFE and other basic components of
a modem. The individual elements of the DM562P
are:
DM6580 Analog Front End (AFE). 48-pin LQFP
package.
DM6588 ITU-T V.90 integrated Processors with
32K bytes SRAM built in 128-pin QFP package
