73M2901CL-IH/F

Overview

The 73M2901CL-IH/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 utilizes a serial interface and functions within a supply voltage range of 2.7 V to 3.6 V, typically at 3.3 V, drawing 9.5 mA. It supports an industrial temperature range from -40°C to +85°C and is housed in a QFN-32 surface-mount package.

Feature Summary

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

Applications

• V.22bis modem implementations
• Network controller systems
• Processor-based communication modules

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm the specific suffix IH/F matches design requirements as it denotes the package and temperature grade. Check current lifecycle status as this series may be subject to discontinuation or limited supply conditions.

Selection Notes

Select this part when a compact V.22bis solution is required for industrial environments. Ensure the system provides a stable 3.3 V supply within the specified tolerance. Verify that the QFN-32 footprint aligns with PCB layout capabilities and thermal management strategies for the target application.

Part Context

This component belongs to the 73M2901CL series of single-chip modems. It shares core specifications with variants like the 73M2901CE-IMR/F but differs in package type and specific suffix coding. The series targets low-power, space-constrained networking applications requiring reliable analog-to-digital conversion and modulation.

Replacement Considerations

Direct substitutes include other members of the 73M2901 family such as the 73M2901CE-IMR/F, provided the package difference between QFN-32 and TQFP-32 is accommodated in the design.
