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).
