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 www.DataSheeFt4MU3.c3o6mPlus-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).
