All voltages referenced to ground VSS. Table lists the ordering information. All devices are lead-free Pb-free and RoHS-compliant.

USB V.92/V.34/V.32bis Controllered Modem With CX20548 SmartDAA®

All tone and pattern detection functions required by the applicable ITU or Bell standards are supported. Oa Electronic Inductor Capacitor. Speakerphone Mode Optional When using the optional CX Codec, the modem includes additional telephone handset, external microphone, and external speaker interfaces which support voice and full-duplex speakerphone FDSP operation. Upon receiving GSTN Cleardown from the remote modem in a non-error correcting mode, the modem cleanly terminates the call.

Ring detection frequency range. Both power dissipation and device noise immunity degrades. Receiver operational amplifier inverting input. Device is marked A on the package Figure With PCM upstream enabled, data transmission supports sending data at line speeds up to 48 kbps.

These country profiles include the following country-dependent parameters: The server must support quick connect profiles. The modem supports four low power modes: The low power mode entered depends on the setting of the —SLP command. The country profiles may be altered or customized by modifying the country-dependent parameters.

Conexant may make changes to this document at any time, without notice. A value of 0 disables the inactivity timer. Conexant makes no commitment to update the information and shall have no responsibility whatsoever for conflicts or incompatibilities dqtasheet from future changes to its specifications and product descriptions.

Both are electrically equivalent and share the same footprint. R and C must be placed very close to pin 6. CXx Current and Power Requirements Provides external connection point for decoupling. Escape sequence detection is disabled by an S2 Register value greater than datasheer An unterminated input can acquire unpredictable voltages through coupling with stray capacitance and internal cross talk.

The punch-style package is shown in Figureand the sawn-style package is shown in Figure The modem connects to host via a logical V. A serial EEPROM is required only if additional storage is required for more country profiles or customized firmware code.

datasheef The modem can automatically determine the speed and format of the data sent from the DTE. 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.

Some AT commands are still valid but may operate differently than in data modem mode. See DC characteristics in Table The CXx has a serial interface and codec interface for connection to the optional CX Codec for speakerphone applications.

Digitized voice data is decompressed and converted to analog form at the original compression quantization sample-per-bits rate then output to the TXA output. Currents are positive when flowing into the device.

The modem features internal RAM memory that enhances the modem’s flexibility.
