2400 bps Modem with SmartDAA 4 for Embedded

Applications

Conexant’s broadband communications portfolio includes a comprehensive

suite of semiconductor solutions that enable the digital home and information

network. Conexant modem solutions deliver a high level of integration and

robust performance. The CX90240 modem device is a simplified design in a

small form-factor which allows for quick time-to-market. The CX90240 modem

supports worldwide DAA and data modes up to 2400bps.

Conexant’s proprietary SmartDAA® 4 line side device builds on three

generations of market leading silicon DAA devices. It reduces Bill of

Material (BOM) cost and necessary board space, making it the most cost

efficient silicon DAA in the market. It eliminates the need for costly analog

transformers, relays and opto-isolators typically used in discrete DAA

implementation for country-specific modem configurations. The result is a

worldwide reduced system cost solution using a single BOM. The SmartDAA4

is system-powered, making it the most reliable and best performing silicon

DAA in the market.

Distinguishing Features

• Modulations

• ITU-T V.22bis (2400 bps)

- V.22 and Bell 212A (1200 bps)

- V.22 fast connect

- V.21 and Bell 103 (300 bps)

- V.23 1200/75 and 75/1200

- V.23 Half Duplex (1200 bps)

• V.42 and MNP2-4 Error Correction

• Serial Interface

• Synchronous/Asynchronous Data Mode -

Hardware and software flow control

• Supports AT Command Set

• Other Protocols

This low cost solution integrates microcontroller (MCU), serial host interface,

ROM, RAM and SmartDAA System Side Device (SSD) functions onto a single

die. The easy-to-use design is pin-to-pin compatible with Conexant’s CX93011

product in a 20-pin Quad Flat-No Lead (QFN) package.

- V.80 Synchronous Access Mode

- V.23 Reverse Mode
