AT commands control the codec bits-per-sample rate. Electronic inductor filtering capacitor. The CX Codec hardware interface signals are described in Table The server must support quick connect profiles.

CXZ from Conexant

After mode entry, AT commands can be entered without aborting the connection. Connect to emitter of transistor Q Un-rectified voltage from telephone line datashwet to detect ring. Active low input asserted to power down the CX Codec. Ring detection frequency range. Conexant makes no commitment to update the information and shall have no responsibility whatsoever for conflicts or incompatibilities arising from future changes to its specifications and product descriptions.

The conductive surface located on the bottom of the package and referred to as pin 17 is connected internally to device analog ground. Some AT commands are still valid but may operate differently than in data modem mode.

Pin 37 is the paddle on the bottom of the package. Request additional country profiles from a Conexant Sales Office. Low speed modulations such as BellA or V. The modem connects to host via a logical V.

Once the voice call is completed, the modem can quickly datashete with the server back to the original data call. When enabled, caller ID information date, time, caller code, and name can be passed to the DTE in formatted or unformatted form. The modem can detect and qualify ring signals and process AT commands. Provides external connection point for decoupling. Single-ended analog data datashheet. The modem dagasheet detect and qualify ring signals. Small, low-profile packages, reduced voltage operation, and low power consumption make this device set an ideal solution for embedded applications.

Conexant assumes no responsibility for errors or omissions in these materials. Full-duplex Receive and Transmit Mode. An unterminated input can acquire unpredictable voltages through coupling with stray capacitance and internal cross talk.

This output can be optionally connected to a low-cost on-board speaker, e. Connect to base of Q The country profiles may be altered or customized by modifying the country-dependent parameters.

Answer tone detection period. Speech received from the telephone line is shaped, converted to analog form, and output datasheeet the speaker or handset. Input signals should never exceed the voltage range from TAM Mode is supported by four submodes: Leave open if not used.

The DIB data channel supports bidirectional half-duplex serial transfer of data, control, and status information between the CXx and the LSD over two lines.
