ZL49011 - (ZL49010 - ZL49031) Wide Dynamic Range DTMF Receiver

This page provides the datasheet information for the ZL49011, a member of the ZL49010 (ZL49010 - ZL49031) Wide Dynamic Range DTMF Receiver family.

Datasheet Summary

Description

The ZL490xx is a family of high performance DTMF receivers which decode all 16 tone pairs into a 4-bit binary code.

These devices incorporate an AGC for wide dynamic range and are suitable for end-to-end signalling.

Features

  • Wide dynamic range (50dB) DTMF Receiver Call progress (CP) detection via cadence indication 4-bit synchronous serial data output Software controlled guard time for ZL490x0 Internal guard time circuitry for ZL490x1 Powerdown option (ZL4901x & ZL4903x) 3.579MHz crystal or ceramic resonator (ZL4903x and ZL4902x) External clock input (ZL4901x) Guarantees non-detection of spurious tones Ordering Information ZL49.
