73M2901CE-IGV/F

Overview

The 73M2901CE-IGV/F is a V.22bis single-chip modem integrating a data pump, controller, and analog front end in a 32-pin TQFP package. It operates from a 2.7 V to 3.6 V supply with typical current consumption of 9.5 mA at 3.0 V. The device supports serial asynchronous and synchronous interfaces and utilizes an 11.0592 MHz crystal oscillator. Key capabilities include DTMF generation/detection, Caller ID support, and energy-based ring detection.

Feature Summary

• Integrates data pump, controller, and analog front end for reduced external component count
• Supports multiple international standards including FCC Part 68, CTR21, and JATE
• Features on-chip hybrid driver and line-in-use/parallel pick-up detection
• Provides direct AT command interface for host control

Applications

• Set-top boxes
• Point-of-sale terminals
• Automatic teller machines
• Utility meters
• Smart card readers

Procurement Notes

Verify the specific suffix IGV/F against the manufacturer's ordering guide to confirm the 32-pin TQFP package variant. Confirm that the component meets RoHS compliance requirements if applicable to your system design. Check for any lead-free soldering specifications required during assembly.

Selection Notes

Select this component when a complete embedded modem solution is needed without external DSPs. Ensure the application requires V.22bis speeds up to 2400 bps. Verify that the host processor can interface via standard serial protocols and that the 3.3 V logic levels are compatible with the system voltage.

Part Context

This part belongs to the 73M2901CE series of low-speed modems by Analog Devices (formerly Teridian). It is pin-compatible with the 73M2901CL hard modem and the 73M1903 soft modem AFE, allowing for flexible design paths within the same system architecture.

Replacement Considerations

The datasheet notes backward compatibility with the 73M2901CL. Designers may consider the 73M2901CL as a functional alternative if hard modem features are preferred, provided the pinout remains identical.
