73M2901CE-IMR/F

Overview

The 73M2901CE-IMR/F is a V.22bis single-chip modem integrating a data pump, controller, and analog front end in a 32-lead QFN package. It operates on a 2.7 V to 3.6 V supply with a typical operating current of 9.5 mA at 3.3 V. The device supports serial interfaces and utilizes an 11.06 MHz crystal oscillator. Designed for low power consumption, it includes standby and power-down modes. The component functions as a complete modem solution for embedded systems requiring reliable low-speed communication.

Feature Summary

• Integrates data pump, controller, and analog front end into a single chip
• Supports V.22bis, V.22, V.21, V.23, Bell 202, and Bell 103 standards
• Includes built-in Caller ID generation and detection capabilities
• Features software-configurable Line-In-Use and parallel pick-up detection

Applications

• Set-top boxes
• Point-of-sale terminals
• Automatic teller machines
• Utility meters
• Vending machines

Procurement Notes

Verify the specific suffix IMR/F against the manufacturer's official ordering guide to confirm the 32-lead QFN packaging and tape-and-reel configuration. Confirm that the component meets RoHS compliance requirements for your target market. Check for any recent product change notices or lifecycle status updates from Analog Devices regarding this part number.

Selection Notes

Select this component when a fully integrated V.22bis modem solution is required to minimize external component count. Ensure the design accommodates the 32-lead QFN footprint and provides separate filtered supplies for analog and digital domains. Verify that the host processor can interface via the asynchronous or synchronous serial ports and support the necessary AT command set.

Part Context

The 73M2901CE belongs to the Teridian/Maxim 73M series of low-speed modems. It is pin-compatible with the 73M2901CL hard modem and the 73M1903 soft modem AFE, allowing for flexible system design. This integration simplifies board layout by combining modem logic and analog line driving into one package.

Replacement Considerations

The datasheet confirms backward compatibility with the 73M2901CL. Designers may consider the 73M2901CL for identical pinouts or the 73M1903 if utilizing a soft modem architecture with an external AFE.
