MAX213CDWR

Drivers, Receivers, Transceivers Overview

The MAX213CDWR is a low-power, full-duplex voice modem transceiver designed for applications requiring reliable data transmission over standard telephone lines. This integrated circuit combines the functions of a modem and a line interface into a single package, supporting V.22bis, V.23, and Bell 212A/103 modulation standards. It operates from a single 5V supply and includes built-in automatic gain control and echo cancellation to ensure signal integrity in noisy environments. The device features a serial interface for easy integration with microcontrollers, facilitating straightforward implementation in fax machines, modems, and telemetry systems without requiring external components for basic operation.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CDWR' indicates the tape and reel packaging variant when ordering. Confirm that the operating temperature range meets your environmental requirements, as industrial grades may differ from commercial variants. Ensure compatibility with your system's voltage levels and serial protocol settings before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Choose this component when a complete, low-pin-count modem solution is required for voice-grade telephone lines. It is suitable for designs where power consumption must be minimized while maintaining compliance with standard modem protocols. Consider the available package options and whether tape-and-reel or tube packaging better suits your assembly process.

Drivers, Receivers, Transceivers Part Context

This part belongs to Texas Instruments' MAX21x series of modem transceivers, which are widely used in legacy communication devices. The MAX213 specifically targets applications requiring full-duplex operation at speeds up to 1200 bps. It serves as a direct replacement for older discrete modem designs, offering reduced board space and simplified design complexity for manufacturers integrating dial-up capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

Check for pin-compatible alternatives such as the MAX213CPE if through-hole packaging is preferred. Verify electrical specifications against competitors like the Rockwell R68391 or similar legacy modem ICs. Ensure that any substitute supports the same modulation standards and interface requirements for seamless integration.
