DESCRIPTION
2
The SAA7327 (CD7 II) is a single chip combining the
functions of a CD decoder, digital servo and bitstream
DAC, especially designed for Video CD applications.
The decoder/servo part is based on the SAA737x (CD7)
and is software compatible with this design. Extra
functions are controlled by use of ‘shadow’ registers
(see Section 7.15.3).
Supply of this Compact Disc IC does not convey an
implied license under any patent right to use this IC in any
Compact Disc application.
PACKAGE
Electronic damping of fast radial actuator during long
jump
Microcontroller loading LOW
High-level servo control option
High-level mechanism monitor
Communication may be via TDA1301/SAA7345
compatible bus or I
On-chip clock multiplier allows the use of 8.4672,
16.9344 or 33.8688 MHz crystals or ceramic
resonators.
