Philips Semiconductors
Preliminary specification
High performance Compact
Disc-Recordable (CD-R) controller
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).
