TAM Mode is supported by four submodes: Pin 37 is the paddle on the bottom of the package. The modem can be awakened by the host sending a single any character typically followed by an AT command or by the modem receiving a qualified ring.

The modem’s internal RAM can be used to load new country profiles, override existing country profiles or add customized firmware datasheett. Analog receiver Analog Output: Position these capacitors very close to the VREF pin.

Oa Electronic Inductor Capacitor.


Speakerphone operation is datashet during Voice Online Command mode after completing dialing or answering. DTR ON prepares the modem to be connected to the telephone line, and maintains the connection established by the DTE manual answering or internally automatic answering. All voltages referenced to ground VSS.


Eatasheet unterminated input can acquire unpredictable voltages through coupling with stray capacitance and internal cross talk. The modem returns to normal mode upon receiving an AT command or receiving a qualified ring.

Conexant customers using or selling Conexant products for use in such applications do so at their own risk and agree to fully indemnify Conexant for any damages resulting from such improper use or sale. The modem supports speed buffering at all line speeds. After dialing, modem operation is controlled by fax commands.

Datasheet Mode features an advanced proprietary speakerphone algorithm which supports full-duplex voice conversation with acoustic, line, and handset echo cancellation. It may also be disabled. The modem can sense speeds of,,,,and bps and the following data formats: Place C near pin 1. These materials dztasheet provided by Conexant as a service to its customers and may be used for informational purposes only. Leave open for Leave open if not used.

The default countries supported are listed in Table The pin QFN package dimensions are shown in Figure Oa Electronic Inductor Output. These country profiles include the following country-dependent parameters: The modem can operate in accordance with requirements of individual countries to prevent misuse of the network by limiting repeated calls to the same number when previous call attempts have failed.


The -TTE command can be used to adjust the voltage thresholds for the telephony extension features. Parameters are constantly adjusted to maintain stability with automatic fallback cs20548 full-duplex to pseudo-duplex operation.
