DescriptionThe 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 14,400bps), 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 and 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 of DM562P 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). 28-pin PLCC package
* DM6588 ITU-T V.90 integrated Processors with 32K bytes SRAM built in 128-pin QFP package
