CMX885L4

Overview

The CMX885L4 is a half-duplex audio, signalling, and data processing integrated circuit manufactured by CML Microcircuits. It operates on a single supply voltage ranging from 3V to 3.6V and utilizes silicon technology. The device supports data transmission rates up to 1200bps using Digital Single-Sideband (DSC) modulation. It is housed in a 48-lead Low Profile Quad Flat Package (LQFP) with dimensions of 7x7 mm. The component is designed for surface-mount installation and is supplied in reel packaging.

Feature Summary

• Integrates half-duplex audio, signalling, and data processing capabilities within a single chip.
• Supports Digital Single-Sideband (DSC) modulation for efficient data transmission.
• Operates on a low-voltage single power supply suitable for portable applications.

Applications

• Two-way radio communication systems
• Telemetry equipment requiring reliable data transmission
• Industrial control interfaces

Procurement Notes

Verify the specific suffix 'L4' corresponds to the LQFP-48 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the required 3V to 3.6V operating voltage range. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component for designs requiring integrated half-duplex baseband processing without external modems. Consider the LQFP-48 package constraints for PCB layout. Evaluate power consumption against system battery life requirements. Compare performance metrics with other members of the CMX885 family if different pinouts or packages are preferred.

Part Context

The CMX885L4 belongs to the CMX885 series of RF wireless miscellaneous components focused on audio and signalling. It shares functional similarities with variants like the CMX885Q3 but differs in package type. The series is designed for general-purpose baseband processing in wireless communication devices.

Replacement Considerations

The CMX885Q3 serves as a direct alternative within the same product family, offering identical functionality in a VQFN-48 package. Verify pinout compatibility and thermal management requirements when substituting between LQFP and VQFN packages.
