2 GENERAL DESCRIPTION
The SAA7390 is a high integration ASIC that incorporates
all of the logic necessary to connect a CD-60 based
decoder to a SCSI or ATAPI host. It also supports a data
path from the host to the CDCEP (compact disc encoder)
for CD-R applications. An 80C32 microcontroller and a
53CF94/92A (or an ATAPI interface device) are required
to provide the full block encode/decode functions. The
following functions are supported:
• Input clock doubler
• Block encoder (using a modified CDB2)
• Block decoder
• CRC checking of Mode 1 and Mode 2, Form 1 sectors
• Red book audio pass through to SCSI or ATAPI
• Sub-code and Q-channel support
• Dedicated S2B interface UART
• Dedicated SPI interface UART
• Up to 4 Mbytes DRAM buffer manager
• Third-level error correction and encoding
• Automatic storage of audio and data
• 80C32 microcontroller interface
• 53CF90 or 53CF92A/B fast SCSI or Wapiti ATAPI
processor interface.
The SAA7390 uses a 33.8688 MHz clock and is capable
of accepting data at eight times (n = 8 or 1.4 Mbytes/s) the
normal CD-ROM data rate. The minimum host burst rate
capability of the SAA7390 is 5 Mbytes/s.
Third level error correction hardware is included to
improve the correction efficiency of the system. The buffer
manager hardware utilizes a ten-level arbitration unit and
can stop the clock to the static microcontroller to emulate
a wait condition when necessary. The host interface is
capable of burst rates to 16.9 Mbytes/s.
