CX06832-12中文资料V.34/Group 3 High Performance Fax Modem Family数据手册Synaptics规格书

描述 Description

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.
