FUNCTIONAL DESCRIPTION
Field rate up-conversion with line flicker reduction

The line flicker reduction in conjunction with field rate
up-conversion is performed by generating a 50 Hz
interlace on the 100 Hz field rate display. Median filtering
supplies the data for the interlaced output fields.

Progressive scan

Progressive scan conversion produces a double number
of lines per field on the output. The field frequency is not
changed, while the line frequency is doubled.

Processing for progressive scan is different for two
successive output fields, e.g. the first output field has a
median operation on the odd lines, while the second has
the median operation on the even lines.

NON-INTERLACE MODE
With non-interlaced progressive scan output, line flicker is

removed because interlace is removed.

I

NTERLACE MODE

With interlaced progressive scan the output line structure
and line flicker is less visible (projection TV).

Progressive scan-Zoom and Noise
reduction IC (PROZONIC)

SAA4990H

Noise and cross-colour reduction

The noise reduction is field recursive with an average ratio
between fresh and over previous fields averaged
luminance and chrominance.

Two operating modes can be used in principal: the fixed
and the adaptive mode (see Table 6).

In the fixed mode, the averaging produces a constant
linear combination of the inputs. Except for k = 1, the fixed
mode should not be used for normal operation, because of
its smearing effects.

In the adaptive mode, the averaging ratio switches softly
on the basis of absolute differences in luminance among
the inputs. When the absolute difference is low, only a
small part of the fresh data will be added. When the
difference is high, much of the fresh data will be taken.
This occurs in either the situation of movement or where a
significant vertical contrast is seen.

To latter remark, note that recursion is done over a field,
and the pixel positions one field apart always have a
vertical offset of one frame line. So averaging is not only
done in the dimension of time but also in the vertical
direction. Therefore averaging vertically on e.g. a vertical
black to white edge would provide a grey result if this was
not adapted for.

The averaging in chrominance is slaved to the luminance
averaging. This implies that differences in the
chrominance are not taken into account for the k-factor
setting.

The noise reduction scheme effectively decreases both
noise and cross-colour patterns.

The cross-colour pattern does not produce an increase of
the measured luminance difference, therefore this pattern
will be averaged over many fields.

Vertical sample rate conversion

The variable vertical sample rate conversion is performed
on top of the noise reduced and progressively scanned
data.

The vertical sample rate conversion is intended to cope
with the various letter box formats, to be displayed on
displays with e.g. 16:9 aspect ratio. For this sample rate
conversion, which usually has both a vertical and a
horizontal component, the vertical sample rate conversion
is taken care of in the PROZONIC, while the horizontal
compression can be done in e.g. TDA8753A or
SAA4995WP.

The vertical sample rate conversion can also be used to
convert from an NTSC 525 lines source to a 625 line
display, by setting a vertical sample rate conversion factor
of

6

⁄5 and necessarily some line-time reduction.

Conversion from 625 to 525 lines is possible with
progressive scan output, by setting a vertical sample rate
conversion of5⁄6.

The principle of vertical sample rate conversion is based
on linear interpolation from two successive lines of video in
a frame to produce an output line in either a field or a
frame.

The vertical sample rate conversion factor can be switched
to the following settings for increasing the number of
output lines w.r.t. the number of input lines; see Table 1.

Table 1 Vertical sample rate conversion factor

Decreasing the number of lines on the display w.r.t. the
number of input lines is only possible with progressive
scan output.

Movie phase detection

While processing video, that was originally film
(25 movement phases per second in the case of 50 Hz
field rates), median filtering is not needed when fields are
combined that have the same movement phase. As this
phase is not generally known, the PROZONIC has a
detection circuit to help determine it. The detection is
based on measurement of absolute luminance differences
between successive input fields, pixel by pixel. These
differences are summed over all active video and give a
number every field. In case of video from film with sufficient
movement, the measured number will alternately be HIGH
and LOW. With the controlling microcontroller, this data
can be filtered appropriately to switch to movie processing
in the correct phase.

The PROZONIC has a provision to generate a rectangular
box, which is position and size programmable. This box
can be used to enable the measurement in the movie
phase detection circuit, only within this rectangle.
Otherwise, the active video part in a field is marked with a
derivative of the RE pulse.

Box generation

A rectangular box is defined by the coordinates of the
left-upper edge (hor_start_box, vert_start_box) and the
right-lower edge (hor_stop_box, vert_stop_box). The
reference for the coordinates are the HD positive edge
(with some processing delay) for the horizontal direction
and the VD positive edge for the vertical.

The box can serve the following purposes:

• Switch between adaptive and fixed k in noise reduction.
If k-fixed is set to 0, then the box switches between
adaptive noise reduced and fully still picture areas. This
provides an option for producing multi picture (still)
images. If no noise reduction is desired in the area
where NR is adaptive, the adaptive setting can be
programmed with k steps to all zeros.

• Switch the movie phase detect measurement to a
defined area of the video.

C

ONTROL SIGNALS

CK

Line-locked clock of nominal 27 or 32 MHz. This is the
system clock, nominally 864 or 1024 × fh, where fh is the
line frequency. Within the PROZONIC, CK is distributed to
different blocks.

HD

Horizontal reference signal. This signal defines with its
rising edge the start phase of the UV 4 :1:1 format. If the
HD signal has a period equal to 4 clock periods, the UV
data will remain in phase without disruptions, once it has
become in phase. For any mismatch between the applied
HD to the UV data phase, an appropriate HD delay can be
set in the PROZONIC. HD is also used to count lines for
boxing.

RE

Master read enable from memory controller or
ECOBENDIC. This signal controls the memory read
enable if only one field memory is present. To control two
field memories, the PROZONIC generates RE1, RE2 and
WE2 from RE. The vertical sample rate conversion
function has a major influence on these signals.

RE1

Read enable for FM1, processed from RE by PROZONIC.

AUX

Spare output from line-sequencer.

VD

Field frequent reset signal, used in PROZONIC to reset
line counting for boxing. The rising edge of VD is taken as
reference. This may be the display related vertical pulse.

SNRST

Field frequent asynchronous reset signal, used in
PROZONIC to reset the communication with
microcontroller. After the rising edge of SNRST,
communication is in its defined state. SNRST is also used
to define the initial phase of the line-sequencer.

SNCL

microcontroller interface clock signal. This signal is
transferred asynchronous to CK by a microcontroller
(UART of 8051 family, mode 0) as communication clock
signal at a frequency of 1 MHz.

SNDA

microcontroller interface data signal. This signal is
transferred or received (asynchronous to CK) by a
microcontroller (UART of 8051 family, mode 0) as
communication data signal at 1 MBaud, related to SNCL.

E

XTERNAL CONTROL

The PROZONIC is controlled via the microcontroller
(SNERT) interface, by sending an address byte and a data
byte to it, with the controllable items as in the register
descriptions in Tables 2 and 3.

Microcontroller interface (SNERT)

In the microcontroller interface the external signals SNDA
and SNCL are processed to address and data. Data
enable pulses are derived from the received addresses.
The data enable pulses are used elsewhere for input
enabling the delivered data into various control registers.

The microcontroller interface operates in a few stages:

1. SNCL positive and negative edges are sampled

2. on each negative edge of SNCL and SNDA data is
shifted in a shift register

3. starting from phase 0, a counter counts positive edges
of SNCL

4. during phase 7, but waited for a negative edge of
SNCL, so after the 8th negative edge of SNCL, an
address latch enable pulse is made, whereby the shift
register contents are taken over in the address register

5. in the address range 10H to 27H, the addresses are
decoded in two steps

6. during phase 15, but waited for a negative edge of
SNCL, so after the 16th negative edge of SNCL, the
address has been decoded and will be passed to any
of the data enable pulses.

For each of the functions vert_start_box and
vert_stop_box, two addresses are used, in which the LSB
from the address is taken as an extra MSB for the data.
This is done because vert_start_box and vert_stop_box
must be supplied with 9-bit data. All other data from the
SNERT-bus has only relevance in the 7:0 range.

During the data phases (phase 8 to 15), each negative
edge produces a shift pulse for the movie phase detect
circuit that produces output data on the SNDA signal. The
data enables for the movie phase detect circuit are active
in all of the data phases, when an address 26 or 27 has
been decoded.

After an MPD read transmission it is necessary to send a
second (dummy) transmission to the PROZONIC.

APPLICATION INFORMATION

The basic application of PROZONIC in a feature box is
shown in Fig.15. Here, apart from the data streams, the
‘timed control data’ streams indicate that some memory
control signals have to be processed by the PROZONIC,
in order to let the vertical sample rate conversion function
correctly.

Horizontal scaling factors are performed by the memory
controller SAA4951WP/SAA4952H.

All basic clock signals in the feature box are provided by
the memory controller, nominal frequencies on the double
scan parts of the system are 27, 32 or 36 MHz. In any case
the display frequency is decoupled from the acquisition
clock.

The memory controller supplies the deflection processor
with clock, horizontal and vertical pulses.

The SNERT-bus is used to control the PROZONIC at a
data rate of typically 1 Mbits/s.

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

“IC Package Databook”

(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 more
information, refer to the Drypack chapter in our

“Quality

Reference Handbook”

(order code 9397 750 00192).

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 techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °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, 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.

Even with these conditions, do not consider wave
soldering the following packages: QFP52 (SOT379-1),
QFP100 (SOT317-1), QFP100 (SOT317-2),
QFP100 (SOT382-1) or QFP160 (SOT322-1).

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 diagonally­opposite 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.
