DM562AP

V.90 Integrated Data/ Fax/Voice/Speakerphone

Modem Device Single Chip with Memory Built in

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

33,600bps), fast connection, 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, Set-Top-Box (STB),

Point-Of-Sale (POS), and Multi-Function Peripheral

(MFP) FAX application. It provides a low cost,

highly reliable, maximum integration, with the

minimum amount of supports 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, synchronous/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

DM562AP V.90 Integrated Data/ Fax/Voice/Speakerphone Modem Device Single Chip with Memory Built in DM6588A can not assert PME# from D0. But can Assert PME# from D3(hot) and D3(cold). Hence the Ring to PME# circuit must check the power state. If ring comes at D0 power state, it can not assert PME#. Software will enable its use by setting the PME_En bit in the PMCSR. It must continue to assert PME# until software either clears the PME_En bit or clears the PME_Status bit.
