CMX7164Q1-TR1K

Overview

The CMX7164Q1-TR1K is a multi-mode wireless data modem IC manufactured by CML Micro. It supports GMSK, GFSK, 2/4/8/16-FSK, 4/16/32/64-QAM, and V.23 modulation schemes with configurable Adaptive Coded Modulation (ACM). The device operates on a 3.0V to 3.6V power supply and utilizes a 64-VQFN package. It features direct connection to zero IF receivers, reconfigurable digital IF filters, and read/write 128-byte FIFOs. Symbol rates range from 1,200 to 20,000 symbols/s depending on the Function Image™ configuration.

Feature Summary

• Supports multiple modulation schemes including GMSK, FSK, QAM, and V.23
• Enables Adaptive Coded Modulation for dynamic block size and coding rate selection
• Features high-performance I/Q radio interface for direct connection to zero IF transceivers
• Includes reconfigurable digital IF filters and deviation control without manual trim

Applications

• High-performance narrowband data radio
• Telemetry, SCADA, and M2M data modems
• Satellite communications
• Software Defined Radio (SDR)
• FCC Part 90 spectral efficiency applications

Procurement Notes

Verify the specific ordering suffix TR1K indicates tape and reel packaging when sourcing components. Confirm that the component meets RoHS3 compliance standards as documented in manufacturer specifications. Ensure compatibility with the required host microcontroller interface protocols before finalizing procurement plans.

Selection Notes

Select this component for designs requiring flexible modulation support across various wireless standards. The FirmASIC® technology allows for custom modulation scheme implementation via Function Image™ uploads. Verify that the system architecture can accommodate the 64-VQFN package dimensions and thermal requirements for optimal performance.

Part Context

This part belongs to the CMX7164 family of multi-mode wireless data modems. It is designed to replace discrete codec and DSP solutions by integrating complete modem functions into a single IC. The component is often paired with CML's RF devices like the CMX998 transmitter or CMX994 receiver for integrated communication systems.

Replacement Considerations

Direct substitutes within the same package and pinout are not explicitly listed in public documentation. Consider evaluating other members of the CMX7164 family, such as the CMX7164Q1, ensuring that any alternative matches the required modulation capabilities and physical footprint constraints.
