FM336Plus

V.34/Group 3 High Performance Fax Modem Family

The Conexant™ FM336Plus High Performance Fax Modem family offers

ITU-T V.34 half-duplex mode operation that supports synchronous Group 3

facsimile send and receive speeds up to 33600 bits per second (bps).

The FM336Plus-D and FM336Plus-D90 support ITU-T V.34 duplex data

and synchronous/asynchronous modes with rates up to 33600 bps. The

FM336Plus-D90 also supports ITU-T V.90 PCM mode, which can receive

data at speeds up to 56 kbps.

The device has low voltage operation and is housed in a 100-pin Plastic Quad

Flat Package (PQFP). The modem’s small size and low power consumption

allow the design of compact system enclosures for use in industrial, office, and

home environments. Table 1 lists the FM336Plus Modem Family models and

features.

Utilizing V.34 and V.90 techniques to optimize modem configuration for line

conditions, the modem connects at the optimal selected data rate that the

channel can support from 2400 bps up to 56000 bps. The modem can operate

over the Public Switched Telephone Network (PSTN) through a line terminator

provided by a Data Access Arrangement (DAA).

The FM336Plus is backward pin compatible with the previous Conexant FM336

fax modem, and supports all features of the FM336 family. The FM336Plus also

has numerous feature and performance enhancements. For more information

on the enhancements, refer to the FM336Plus High Performance Fax Modem

Designer’s Guide (document 101360).
