RC224ATL/224ATLV

EmbeddedModem Family

The new Conexant RC224ATL utilizes a new integrated data pump/controller to allow

the device to directly connect to host processors that are 3.3 V I/O capable. The codec

used in the new part is the same as the codec used in the existing RC224ATL. The

new device is form, fit, and function compatible with the existing device. This means

there are no hardware and software differences between the existing and the new part,

with one exception. The 3.3 V I/O capable part incorporates 3.3 V compatible digital

I/O buffers, hence requiring 3.3 V digital supply instead of 5 V digital supply.

In addition, unlike the current version of RC224ATL, the new part provides both

data and fax capabilities.

Data modes, controlled by an industry standard 2400 AT command set, can

transmit and receive up to 2400 bps.

Fax modes, controlled by a built-in EIA-578 Class 1 command interface, provide

Group 3 transmit and receive functions.
