SDRAM
9 Mbytes/s in bursts of 128 bytes
Dedicated input for audio and video in PES or ES in byte
wide. Data input rate:
9 Mbytes/s in byte mode.
Accompanying strobe signals distinguish between audio
and video data
Dedicated compressed data input compatible with the
VLSI VES2020/2030 demultiplexers; video is received
in byte format and audio serially
Audio and/or video can also be input via the CPU
interface in PES/ES in 8 or 16-bit parallel format up to a
peak data rate of 9 Mbytes/s
Single 27 MHz external clock for time base reference
and internal processing. Internal system time base at
90 kHz can be synchronized via CPU port. All required
decoding and presentation clocks are generated
internally
Flexible memory allocation under control of the external
CPU enables optimized partitioning of memory for
different tasks
Boundary scan testing implemented
External SDRAM self test
Supply voltage 3.3 V
Package QFP160.

decoding/display processes
Stand-alone mode can be used by applications requiring
still pictures manipulations
Output interface at 8-bit wide, 27 MHz UYVY
multiplexed bus
Horizontal and vertical pan and scan allows the
extraction of a window from the coded picture
Flexible horizontal scaling from 0.5 up to 4 allows easy
aspect ratio conversion including support
for 2.21 : 1 aspect ratio movies. In case of shrinking an
anti-aliasing pre-filter is applied
Vertical scaling with fixed factors 0.5, 1 or 2. Factor 0.5,
realizing picture shrink. Factor 2 can be used for
up-conversion of pictures with 288 (240) lines or less.
Vertical down-scaling with 0.75 factor, realizing letter
box conversion
Horizontal and vertical scaling can be combined to scale
pictures to
1
/
4
their original size, thus freeing up screen
space for graphic applications like electronic program
guides
Non full screen MPEG pictures will be displayed in a box
of which position and background colour are adjustable
by the external microcontroller
Nominal video input buffer size for ml@mp 2.7 Mbit
Video output may be slaved to internally (master)
generated or externally (slave) supplied HV
synchronization signals. The position of active video is
programmable. Display phase is not affected by MPEG
timebase changes.

Graphics features
Graphics are presented in boxes independent of video
format
Screen arrangement of boxes is determined by display
list mechanism which allows for multiple boxes,
background loading, fast switching, scrolling and fading
of regions
Support of 2, 4, 8-bit/pixel in fixed bit maps format or
coded in accordance to the DVB variable/run length
standard for region based graphics
Display colours are obtained via colour look up tables.
CLUT output is YUVT at 8-bit for each signal component
thus enabling 16 M different colours and 6-bit for T
which gives 64 mixing levels with video,
(T = transparency).
Bit-map table mechanism to specify a sub set of entries
if the CLUT is larger than required by the coded bit
pattern. Supported bit-map tables are 16 to 256,
4 to 256 and 4 to 16.
Graphics boxes may not overlap vertically. If 256 entry
CLUT has to be down loaded, a vertical separation of
1 line is mandatory.
Optimized memory utilization in MPEG video decoding
allows for a storage capacity of 1.2 Mbit for graphics bit
maps. Flexibility in memory control enables larger
capacity in a lot of applications. Moreover variable
length/run length encoding makes better use of
available memory capacity for graphics bit maps thus
making full screen graphics at 8-bit/pixel feasible.
Fast CPU access (9 Mbytes/s) enables full 1.2 Mbit bit
map update within 20 ms
Internal support for fast block moves in external SDRAM
Graphics mechanism can be used for signal generation
in the vertical blanking interval. Useful for teletext, wide
screen signalling, closed caption, etc.
Support for a single down loadable cursor of 1k pixel
with programmable shape. Supported shapes are
8
128 pixels, 16
64 pixels, 32
32 pixels,
64
16 pixels and 128
8 pixels.
Cursor colours obtained via 4 entry CLUT with YUVT at
6,4,4 respectively 2 bits. Mixing of cursor with
video + graphics in 4 levels.
Cursor can be moved freely across the screen without
overlapping restrictions.

SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our
"Data Handbook IC26; Integrated Circuit Packages"
(order code 9398 652 90011).
Reflow soldering
Reflow soldering techniques are suitable for all QFP
packages.
The choice of heating method may be influenced by larger
plastic QFP packages (44 leads, or more). If infrared or
vapour phase heating is used and the large packages are
not absolutely dry (less than 0.1% moisture content by
weight), vaporization of the small amount of moisture in
them can cause cracking of the plastic body. For details,
refer to the Drypack information in the
"Data Handbook
IC26; Integrated Circuit Packages; Section: Packing
Methods".
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 50 and 300 seconds depending on heating
method. Typical reflow peak temperatures range from
215 to 250
C.
Wave soldering
Wave soldering is not recommended for QFP packages.
This is because of the likelihood of solder bridging due to
closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.
If wave soldering cannot be avoided, for QFP
packages with a pitch (e) larger than 0.5 mm, the
following conditions must be observed:
A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave)
soldering technique should be used.
The footprint must be at an angle of 45
to the board
direction and must incorporate solder thieves
downstream and at the side corners.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Maximum permissible solder temperature is 260
C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150
C within
6 seconds. Typical dwell time is 4 seconds at 250
C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Repairing soldered joints
Fix the component by first soldering two diagonally-
opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300
C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320
C.
CAUTION
Wave soldering is NOT applicable for all QFP
packages with a pitch (e) equal or less than 0.5 mm.
