V.90/K56flex/V.34/V.32bis Modem Device Sets with Microcontroller (L2702), Modem Data Pump (P9373), SmartDAA(20463), and Optional Voice Codec (20437) for Low Power Applications
General Description
The SmartACFL device set, comprised of separate microcontroller (MCU), modem data pump (MDP), and line side device (LSD) devices, provides the processing core for a complete modem design. The optional Voice Codec (VC) supports voice/full-duplex speakerphone (FDSP) operation with interfaces to a microphone and speaker and to a telephone handset/headset (S models). The S model can also be ordered with an RCDSVD Speech Codec Processor (SCP) in a 100-pin PQFP to support DSVD.
Modem operation, including dialing, call progress, telephone line interface, telephone handset interface, voice/speakerphone interface, and host interface functions are supported and controlled through the V.250, V.251, and V.253-compatible command set.
The modem hardware connects to the host via a parallel, serial, or PC Card interface. The OEM adds discrete components as required by the modem model and the application to complete the system (Table 1). These components may include a crystal circuit, EEPROM, DIB components, telephone line interface, optional voice/speakerphone interface, and optional cellular/GSM interface.Detailed Features
