DM336P

V.34 Integrated Data/ Fax/Voice/Speakerphone Modem Device Set

General Description

The DM336P 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 33,600bps), Fax (up to 14,400bps), Voice

and Full Duplex Speaker-phone functions to comply

with various international standards.

The DM336P modem’s 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 DM336P are:

The design of the DM336P 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 DM336P

modem can operate over a dial-up network (PSTN) or

2 wire leased lines.

• DM6380 Analog Front End (AFE). 28-pin PLCC

package

• DM6381 ITU-T V.34 Transmit Digital Signal

Processor (TX DSP). 100-pin QFP package

• DM6382 ITU-T V.34 Receive Digital Signal

Processor (RX DSP). 100-pin QFP package

• DM6383 Modem Controller (MCU) built in Plug &

Play (PnP). 100-pin QFP package

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.
