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.

CLOSED LOOP SENSORS
Closed loop current sensors measure AC, DC and impulse currents over 0-25, 0-50, 0-100, 0-600 and 0-1200 Amp ranges. The CSN Series is based on the principles of the Hall effect and the null balance or zero magnetic flux method (feedback system). The magnetic flux in the sensor core is constantly controlled at zero. The amount of current required to balance zero flux is the measure of the primary current flowing through the conductor, multiplied by the ratio of the primary to secondary windings. This closed loop current is the output from the device and presents an image of the primary current reduced by the number of secondary turns at any time. This current can be expressed as a voltage by passing it through a resistor

FEATURES
• Current sensing up to 1200 amps
• Measures AC, DC and impulse currents
• Lowest cost/performance ratio
• Rapid response, no overshoot
• High overload capacity
• High level of electrical isolation between primary and secondary circuits
• Small size and weight
