Specifications and features

Overview: The Conexant SMXXD Modem is a full-featured, controller-based modem that integrates modem controller (MCU), modem data pump (MDP), 256 KB ROM, 32 KB RAM, and analog line interface codec functions into a single package.

General Modem Features:

• Data modem with various functions such as Quick connect, Modem-on-Hold, and PCM upstream functions.
• Supports ITU-T V.92/V.90, V.34, V.32bis, V.32, V.29, FastPOS (V.29), V.22bis, V.22, V.22 Fast Connect, V.23, V.21, Bell 212A, and Bell 103.
• Supports V.250 and V.251 commands.
• Data compression and error correction through V.44 data compression, V.42 bis and MNP 5 data compression, V.42 LAPM and MNP 2-4 error correction.
• Fax modem send and receive rates up to 14.4 kbps through V.17, V.29, V.27 ter, and V.21 channel 2. Supports EIA/TIA 578 Class 1 and T.31 Class 1.0.
• V.80 synchronous access mode that supports host-controlled communication protocols with H.324 interface support.
• Interfaces with optional external ROM/flash ROM, RAM, and/or optional serial EEPROM.
• Data/Fax/Voice call discrimination.
• Hardware-based modem controller and digital signal processor (DSP).
• Support for many country-specific DAA configurations such as on-hook and/or off-hook Caller ID detection for selected countries, call progress, blacklisting, internal ROM includes default values for 29 countries, and additional and modified country profile can be stored in internal SRAM.
• Telephony/TAM with V.253 commands, 2-bit and 4-bit Conexant ADPCM, 8-bit linear PCM, and 4-bit IMA coding, 8 kHz sample rate, and concurrent DTMF, ring, and Caller ID detection.
• Full-duplex speakerphone (FDSP) mode using optional CX20442 Voice Codec (S models) with microphone and speaker interface, telephone handset or headset interface, acoustic and line echo cancellation, microphone gain and muting, and speaker volume control and muting.
• Built-in host/DTE interface with parallel 16550A UART-compatible interface up to 230.4 kbps and serial ITU-T V.24 (EIA/TIA-232-E)logical interface up to 115.2 kbps.
• Downloadable architecture, direct mode (serial DTE interface), flow control and speed buffering, automatic format/speed sensing, and serial async/sync data; parallel async data.
• Thin packages support low profile designs (1.6 mm max. height) with CX06833 Modem device in 144-pin TQFP and CX20442 VC in 32-pin TQFP.
• +3.3V operation with +5V tolerant digital inputs and typical power use of CX06833: 191 mW (Normal Mode); 53 mW (Sleep Mode) and CX20442: 5 mW (Normal Mode).
