MB87068 - ADPCM Digital Signal Processor

Download the MB87068 datasheet PDF. This datasheet also covers the MB87067 variant, as both devices belong to the same adpcm digital signal processor family and are provided as variant models within a single manufacturer datasheet.

General Description

The Fujitsu MB87067/MB87068 Digital Signal Processor (DSP) consists of two MB8764 DSPs each with an applications-specific program in the internal ROM.

Together, the MB87067/MB87068 chip set provides all coding/decoding functions required to process Adaptive Pulse Code Modulation (ADPCM) signals.

Key Features

  • High-performance design based on MB8764 DSP (Same electrical and timing specifications. ).

Together, the MB87067/MB87068 chip set provides all coding/decoding functions required to process Adaptive Pulse Code Modulation (ADPCM) signals. The MB87067 provides the encoding function and the MB87068 provides the decoding function. Under direction of the ADPCM programs stored in the two devices, the chip set allows the user to implement a CCITT standard ADPCM CODEC without any program development work.
