ZL49031DDF1

Overview

The ZL49031DDF1 is a dedicated digital tone multifrequency (DTMF) receiver integrated circuit manufactured by Microchip Technology. Designed for high-quality audio reception and decoding, this telecom IC operates at a frequency of 3.579MHz and supports a 5V power supply. It is housed in a compact 20-SSOP package, providing reliable DTMF signal detection capabilities suitable for telecommunications applications requiring precise tone decoding.

Feature Summary

• Dedicated digital tone multifrequency receiver architecture
• Reliable DTMF signal detection functionality
• Compact design optimized for space-constrained environments

Applications

• Telecommunications equipment
• Audio reception systems
• DTMF decoding interfaces

Procurement Notes

Verify the specific suffix 'DDF1' to ensure correct package type and temperature rating. Confirm that the 5V supply requirement aligns with system design constraints. Check for RoHS compliance status through official Microchip documentation before finalizing procurement decisions.

Selection Notes

Select this component when a dedicated hardware solution for DTMF decoding is required. Ensure the operating frequency of 3.579MHz matches the system clock requirements. The 20-SSOP package size should be considered for PCB layout constraints compared to alternative packages like DDE1.

Part Context

This part belongs to Microchip's Telecom IC portfolio, specifically focusing on DTMF receiver solutions. It serves as a specialized component for processing dual-tone multi-frequency signals in communication devices, distinct from general-purpose microcontrollers or memory products offered by the manufacturer.

Replacement Considerations

The ZL49031DDE1 is a documented variant within the same product family. Verify if the package difference between SSOP-20 and the alternative affects board compatibility.
