Preliminary specification

SAA7390

The SAA7390 comprises four major functional blocks:

• The front-end block connects to the external CD-60

based decoder and fully processes the incoming data

stream

• The buffer manager block provides the address

generation and timing control for the external DRAMs

• The ECC block performs the error correction functions in

hardware on the data stored in the DRAM buffer.

• The block encoder function (realized via a modified

CDB2) serializes the data from the buffer, appends the

sync pattern, header, sub-header, third level ECC parity

and EDC bytes as necessary, performs the required

scrambling and outputs them to the CDCEP using a

special data clock (98 clock cycles per word selection

period).
