M-985-01T - Precise Call Progress and Special Information Tone Generator

General Description

The M-985-01 is an integrated circuit precise tone detector for call progress and special information tones (SIT), as defined by CCITT.

The use of integrated circuit techniques allows the M-985-01 to pack the eight filters for call progress detection into a single 22-pin DIP or a 20-pin SOIC.

Key Features

  • Precise detection of call progress tones Linear (analog) input Digital (CMOS compatible), tri-state outputs 22-pin DIP and 20-pin SOIC Single supply 3 to 5 volt (low power CMOS) Inexpensive 3.58 MHz crystal time base Wide dynamic range (30 dB) Lower power consumption (power-down mode) 425 Hz detection Special Information Tone (SIT) Detection.
