CXx DC electrical characteristics are listed in Table Digitized audio data is converted to analog form then output to the TXA output.

Leave open if not used. Outputs transmit signal and impedance matching signal; connect to base of transistor Q Upon receiving GSTN Cleardown from the remote modem in a non-error correcting mode, the modem cleanly terminates the call.

This prevents forward biasing the input protection diodes and possibly entering a latch up mode due to high current transients. The modem cannot process AT commands.

The modem continues to retrain until an acceptable connection is achieved, or until 30 seconds elapse resulting in line disconnect. Calculated voltage is applied to this output to control off-hook and DC VI mask operation.

The modem supports four low power modes: Connect to emitter of transistor Q Shape of Pin 1 indicator on the bottom of package can be different i.

The CXx has a serial interface and codec interface for connection to the optional CX Codec for speakerphone applications. All devices are lead-free Pb-free and RoHS-compliant.

AT commands control the codec bits-per-sample rate. The dictionary is dynamically updated during normal operation. Hands-free full-duplex telephone operation is supported in Speakerphone Mode under host control. This allows the modem to maintain compliance with U. Received analog voice samples are converted to digital form and compressed for daasheet by the host. Third-party datawheet and names are the property of their respective owners.


Connect to digital ground GND. The clock signal passing through the transformer is rectified in the LSD and filtered using external capacitors. Active low input asserted to power down the CX Codec. The modem also supports V. R and C must be placed datasheeg close to pin 6. Frequency and cadence of tones for busy, ringback, congested, warble, dial tone 1, and dial tone 2. These materials are provided by Conexant as a service to its customers and may be used for informational purposes only.


TAM Mode is supported by four submodes: In the command state, the modem ignores RTS. MOH can be executed through either of two methods: All voltages referenced to ground VSS.

If carrier is lost for a time greater than specified by the S10 register, the modem disconnects. The modem can operate in accordance with requirements of individual countries to prevent misuse of the network by limiting repeated calls to the cx205548 number when previous call attempts have failed. C must be placed close to pins 2. If this occurs, retraining may be initiated to attempt recovery depending on the type of connection. Industry standard and shortened answer tone B and V.
