GENERAL DESCRIPTION
SAA7817HL
The SAA7817HL is a device for 6× DVD and 18× CD
playback applications.
This device contains an embedded microcontroller which
can operate as a 33 or 67 MHz equivalent 80C51 and
interfaces to the channel decoder, block decoder and
servo processor.
New features enable superior playability in both CD and
DVD modes.
The block decoder has an embedded DVD video
authentication module and supports up to 64 Mbit of
external SDRAM memory. The data can be fed out in a
number of different configurations including I
2
S-bus,
ATAPI and UDE. This device also includes the option to
bypass the external memory altogether, creating a
bufferless ATAPI or UDE data path solution.
The channel decoder has selectable differential and
single-ended HF inputs, which are compatible with the
TZA1033 and TZA1035 devices. There is an option to
output the data as raw I
2
S-bus via some programmable
data I/O pins. With increased tap setting for the PLL
equalizer compared with the SAA7812 device and
enhanced playability of black dots and scratches, overall
playability has been greatly improved. There are also
benefits due to a new defect detector that allows holding
the HF PLL frequency and slicer settings over a defect.
These, together with an additional limit equalizer lead to
improved tolerance to continuity errors in DVD playback
mode. There are also two extra motor gain settings
compared to the SAA7812 device and support for
copyright protection strategies in games applications.
The servo processor has been upgraded to include an
improved defect detection and handling process, an
integrated envelope detection circuit and also DC offset
compensation on the diode inputs.
