DM560P 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 amodem. 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
