CMX823 - Programmable Paging Tone Decoder

Download the CMX823 datasheet PDF. This datasheet also covers the CMX823-CML variant, as both devices belong to the same programmable paging tone decoder family and are provided as variant models within a single manufacturer datasheet.

General Description

The CMX823 is a high performance, low power, audio tone decoder that can operate on low S/N signals.

Each decoded tone frequency is user-defined to provide the flexibility to operate in a variety of paging, two-way radio and proprietary systems.

Key Features

  • Decodes 32 User-Programmed Tones.
  • Stores Two Lists of 32 Tones to Fast- Switch Between Tone Sets.
  • Configurable Decode Response Time and Decode Bandwidths.
  • Low Power: 0.75mA at 2.7V (typ. ) and 'Zero-Power' Powersave Mode.
  • Superior Signal to Noise Performance.
  • Low Cost 3.58MHz Xtal/Clock.
  • Small 16-pin TSSOP Package.
