General Description
The DM560P integrated modem is a four chipset
design that provides a complete solution for state-
of-the-art, voice-band Plain Old Telephone Service
(POTS) communication. The modem provides for
Data (up to 56,000bps), Fax (up to 14,400bps),
Voice and Full Duplex Speaker-phone functions to
comply with various international standards.
The design of the DM560P is optimized for desktop
personal computer applications and it provides a low
cost, highly reliable, maximum integration, with the
minimum amount of support required. The DM560P
modem can operate over a dial-up network (PSTN)
or 2 wire leased lines.
The modem integrates auto dial and answer
capabilities, synchronous and asynchronous data
transmissions, serial and parallel interfaces, various
tone detection schemes and data test modes.
The DM560P 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 DM560P
are:
DM6580 Analog Front End (AFE). 28-pin PLCC
package
DM6581 ITU-T V.90 Transmit Digital Signal
Processor (TX DSP). 100-pin QFP package
DM6582 ITU-T V.90 Receive Digital Signal
Processor (RX DSP). 100-pin QFP package
DM6583 Modem Controller (MCU) built in Plug &
Play (PnP). 100-pin QFP package
