73M2901CL-IGV/F

Overview

The 73M2901CL-IGV/F is a single-chip V.22bis modem manufactured by Analog Devices Inc./Maxim Integrated, designed for serial communication applications. It operates within a supply voltage range of 2.7 V to 3.6 V and supports data rates up to 2.4 kb/s. The device integrates DPSK, DTMF, FSK, and QAM modulation capabilities. It is housed in a 32-pin TQFP package with dimensions of 6.8 x 6.8 x 1 mm. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates complete V.22bis modem functionality into a single chip
• Supports multiple modulation schemes including DPSK, DTMF, FSK, and QAM
• Features low-voltage operation suitable for portable systems

Applications

• Serial communication modems
• Industrial control systems requiring V.22bis compliance
• Portable data transmission devices

Procurement Notes

Verify the exact suffix 'CL' against official datasheets, as standard listings often reference 'CE'. Confirm availability status, as this component may be discontinued or subject to limited supply constraints. Ensure the 32-pin TQFP package matches the target PCB footprint requirements before procurement.

Selection Notes

Select this component when a standalone V.22bis modem solution is required without external DSP processing. Compare pinout compatibility with existing designs using the CE variant. Verify that the 2.4 kb/s data rate meets system throughput needs and that the 3.3 V nominal supply aligns with the power architecture.

Part Context

This part belongs to the Maxim Integrated 73M series of modem chips. It serves as a specialized communication interface for legacy telephone line data transmission standards. The product line focuses on integrating analog front-end and digital baseband processing for cost-effective modem implementations.

Replacement Considerations

The 73M2901CE-IGV/F is a documented alternative within the same family. Verify if the 'CL' suffix denotes specific environmental or reliability grades compared to the 'CE' version. Check for pin-to-pin compatibility to ensure direct replacement feasibility.
