DVSR CODEC

The MX802 Data/Voice Storage and Retrieval (DVSR) Codec contains a Continuously Variable Slope Delta Modulation (CVSD) encoder and decoder as well as control and timing circuitry for up to 4Mbits of external DRAM. As a member of the DBS800 series, it also contains interface and control logic for the “C-BUS” serial interface.

FEATUREs
• DVSR (Data/Voice Storage and Retrieval) Codec
• CVSD Codec Encoder and Decoder
• Control and Timing Circuitry for 4Mbits of external DRAM
• Low Power Operation
• Member of DBS800 Family (C-BUS Compatible)

APPLICATIONs
• Answering Machines where an incoming speech message is stored for later recall
• Busy Buffering, in which an outgoing speech message is stored temporarily
• Automatic transmission of pre-recorded alarm or status messages.
• Time Domain Scrambling of Speech messages
• VOX control of transmitter functions
• Temporary Data Storage, such as buffering of over-air data transmissions
