CMX602BP3

Telecom Overview

The CMX602BP3 is a Calling Line Identifier (CLID) integrated circuit manufactured by CML Microcircuits. Designed for telephone line applications, it detects and decodes FSK and DTMF signaling formats to extract caller information. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports serial interface communication. It features low power consumption suitable for battery-operated systems and includes built-in filtering for noise immunity. The component is housed in a surface-mount TSSOP-20 package, ensuring compatibility with automated assembly processes.

Telecom Feature Summary

• Supports detection of FSK and DTMF calling line identification signals
• Integrated low-noise amplifier and signal conditioning stages
• Serial digital output interface for microcontroller integration
• Wide operating voltage range supporting various system designs

Telecom Applications

• Caller ID display units for residential telephones
• PBX systems requiring incoming call identification
• VoIP gateways with analog trunk interfaces
• Smart home automation hubs with landline connectivity

Telecom Procurement Notes

Verify the specific suffix 'BP3' against the official CML Micro datasheet to confirm pinout and packaging details. Check current availability status as older CLID components may have limited stock or obsolescence notices. Ensure RoHS compliance documentation matches the required manufacturing standards for your region before finalizing orders.

Telecom Selection Notes

Select this component when FSK/DTMF CLID decoding is required without external DSP processing. Compare power consumption metrics against alternative solutions if battery life is critical. Verify that the serial interface timing aligns with the target microcontroller's capabilities. Consider thermal performance within the TSSOP-20 enclosure for enclosed designs.

Telecom Part Context

This part belongs to the CMX602 family of calling line identifiers from CML Microcircuits. The series provides robust signal processing for legacy telephone networks. Variants within the family may differ in packaging or minor electrical characteristics. The CMX602BP3 represents a specific configuration optimized for standard surface-mount assembly requirements.

Telecom Replacement Considerations

Direct replacements include other CMX602 variants such as CMX602A or CMX602E, provided pinouts are compatible. Cross-reference with Holtek HT9032 series for functional equivalence in CLID applications. Verify interface protocols match before substituting to avoid firmware modifications.
