9.1
Introduction
9.1.1
Features
The SD4.0SA_CH modules consist of the Mercury 3 Loader
VAL6013/01 (from Philips Optical Storage), and a Mono Board.
The module is capable of analogue video (with option for digital
YUV video) and digital audio and SACD decoding.
9.1.2
Differences
The DVD-module SD4.0SA_CH is based on its predecessor
the SD4.0, with similar functional block partitioning. However,
the implementation of most functional blocks has been
redesigned due to a new:
•
Furore IC for SACD decoding.
•
Module interface.
•
Mechanical construction.
9.1.3
Modules
The main modules are:
•
Mercury 3 Loader - VAL6013/01.
•
Mono Board.

The SD4.00_SA_CH (SACHI_4) is the 2nd generation Philips
Architectural Standard Design of SACD mono board based on
Furore 2, and will be used in the new generation of SACD
players. It is designed in a multi-task way so that it can support
the following optional main functions:
•
SD4.00_SA_CH: Support SACD player with 5-disc
changer.
•
SD4.00_SA: Support SACD player with single-disc.
•
SD4.00_CH: Support DVD player with 5-disc changer but
without SACD playback.
•
SD4.00_SA_I2C: Support SACD player with single-disc
and I2C slave.
The SD4.00_SA_CH (SACHI_4) module consist of the
following key components:
1.
OPU: Mercury 2 Loader VAL6011/14 (slim type) for a
single-disc SACD player, or DVD VAM6001/14 mechanism
for a 5-disc SACD changer.
2.
Front-end: M2 Basic Engine.
3.
Back-end: DVD Host Processor STi55xx and Furore 2
SACD DSD/DST decoder.
4.
Power supply: To convert the PSU voltages to the correct
values.
5.
Reset circuit: This circuit that the booting of the several
devices on the mono board takes place in the correct order.
9.2.1
