Features: An audio frequency digital-to-analog converter which accepts digital data in serial format, as generated by the PCM ENCODER module. Frame synchronisation may be achieved either from an external synchronisation signal or may be extracted from the embedded frame synchronisation code generated by the PCM ENCODER module. The bit clock provided must be synchronised and in-phase with the incoming digital data. Two PCM DECODER modules may be connected in parallel, with the appropriate control signal, to decode the data generated by two PCM ENCODER modules operating in Time Division Multiplex mode. Specifications: Input PCM DATA serial, TTL level data stream in offset binary format Input Format 8 bits, including frame synchronisation bit as LSB Digitising Formats 7-bits linear, 4-bits linear, and 4-bits companded The PCM DECODER is a module from Emona.
