MT3171B - Wide Dynamic Range DTMF Receiver

This page provides the datasheet information for the MT3171B, a member of the MT3370B Wide Dynamic Range DTMF Receiver family.

Description

The MT3x7xB 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 (50 dB) DTMF Receiver Call progress (CP) detection via cadence indication 4-bit synchronous serial data output Software controlled guard time for MT3x70B Internal guard time circuitry for MT3x71B Powerdown option (MT317xB & MT337xB) 4.194304 MHz crystal or ceramic resonator (MT337xB and MT327xB) External clock input (MT317xB) Guarantees non-detection of spurious tones Ordering Information.
