73M2901CL-IGT/F

Overview

The 73M2901CL-IGT/F is a single-chip V.22bis modem manufactured by Analog Devices Inc./Maxim Integrated, designed for network controller and processor IC applications. It operates at a data rate of 2.4 kb/s with an internal frequency of 11.06 MHz. The device features a serial interface and functions within a supply voltage range of 2.7 V to 3.6 V, drawing 9.5 mA during operation. It is housed in a QFN-32 package suitable for surface mount installation and supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates complete V.22bis modem functionality into a single chip architecture
• Supports standard serial communication interfaces for system integration
• Operates reliably across extended industrial temperature environments

Applications

• V.22bis single-chip modem implementations
• Network controller and processor IC systems
• Industrial communication equipment requiring robust modem connectivity

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and pin alignment before soldering. Ensure compliance with RoHS directives as specified in official documentation. Review end-of-life notices for long-term supply planning. Validate electrical parameters against current design requirements prior to procurement.

Selection Notes

Select this component for designs requiring integrated V.22bis modulation capabilities without external modem chips. Consider the QFN-32 footprint for space-constrained PCB layouts. Verify thermal management strategies for operation within the specified -40°C to +85°C range. Ensure power supply rails meet the 2.7 V to 3.6 V operating window. Evaluate serial interface compatibility with host microcontrollers or processors.

Part Context

This part belongs to the 73M2901CE series of single-chip modems from Analog Devices/Maxim Integrated. It serves as a specialized solution for legacy telecommunication protocols within modern embedded systems. The component integrates analog front-end processing with digital baseband functions. It represents a consolidated approach to implementing standard dial-up modem standards in compact form factors.

Replacement Considerations

The 73M2901CL-IGVR/F is a documented substitute offering identical electrical specifications but utilizes a TQFP-32 package instead of QFN-32. Verify mechanical fit and pinout compatibility when considering this alternative for board redesigns.
