RC224ATLV
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.
