General Description

The DM562AP 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

ban0bps), Voice and Full Duplex Speaker-phone

functions to comply with various international

standards.

The design of the DM562AP 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

DM562AP 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 DM562AP 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 DM562AP

are:

•

DM6580 Analog Front End (AFE). 48-pin LQFP

package.

•

DM6588A ITU-T V.90 integrated Processors

with 32K bytes SRAM built in 128-pin QFP

package
