The SDA 9280 accepts four different data input formats (Ι2C signal: INFOR). Three
sample frequency relations of Y:(B-Y):(R-Y) are possible (4:1:1 or 4:2:2 or 4:4:4).
Semiconductor Group
11
1998-02-01
SDA 9280 B22
The representation of the samples is programmable separately for luminance and
chrominance signals as positive dual code or 2’s complement code
(Ι2C signals: INCODL, INCODC)
The amplitude resolution for each input is 8 Bit, the maximal clock frequency is 30 MHz.
Consequently the SDA 9280 is dedicated for applications in high quality digital video
systems. The data input stages and the internal data multiplexer operate with a special
data input clock (SCA). For applications in the Siemens MEGAVISION® System the
SCA-clock is identical with the memory output clock. A separation of the data input clock
and the system clock is relevant to handle the special data format occurring at “zoom”
operation mode. For other applications SCA can be connected with CLL.
Note: Zoom mode causes a greater signal delay time of the whole IC. Zoom mode
identification is performed automatically.

Frequency Response of a Filter Stage of Interpolator 1
(ƒs is the sampling frequency at the output of the interpolation filter stage)
For internal processing the 4:4:4 parallel format is used. The 4:1:1 data are interpolated
by two interpolation filters having the same frequency response (see figure 3) to the
4:4:4 format. Each filter performs a doubling of the sample frequency. The 4:4:4
interpolation of 4:2:2 data is done by the second filter stage. The diagram shows the
frequency response of one filter stage.
Semiconductor Group
12

SDA 9280 B22
Interpolation filtering can be switched off for each stage separately (Ι2C signals: INT422,
INT444). Then each sample is simply repeated twice. Activation of interpolation filtering
is recommended because analog postfiltering of chrominance signals then can be
greatly simplified (see also Interpolator 2).
2.3
Luminance Peaking Filter
The luminance peaking filter improves the over all frequency response of the luminance
channel. It consists of three filters working in parallel. They have low pass (LP(z)), band
pass (BP(z)) and high pass (HP(z)) characteristics. Their gain factors are separately
programmable (Ι2C signals: LCOF, BCOF, HCOF) according to the following equations:
LCOF * LP(z) + BCOF * BP(z) + HCOF * HP(z)
with:
LCOF = 0 ... [1/4] ... 3/2, 2
BCOF = 0 ... [1/4] ... 3, 7/2, 4, 5
HCOF = 0 ... [1/4] ... 3, 7/2, 4, 5
LP(z) = 1/16 * (1 + z-1)4
BP(z) = -1/8 * (1 - z-2)2
HP(z) = 1/16 * (1 - z-1)4
An amplification of up to 14 dB at the half of the sample frequency is available. The high
pass and band pass filters are equipped with a common coring algorithm. It is optimized
to achieve a smooth display of grey scales, not to improve the signal-to-noise ratio.
Therefore no artifacts are produced. Coring can be switched off (Ι2C signal: COR).
Note: The peaking filter may shift the black level of the signal. This has to be considered
for black level insertion (see Insertion Facilities).
A delay line for the luminance signal enables an adaption to the delay of the chrominance
signals. A range of -8 to +7 clock periods of the system clock CLL is programmable
(Ι2C signal: YDEL1).
An additional special filtering is available for compensating a non linear phase response
of the analog part of the signal path.
(1 + PHACOM) * z–1 - PHACOM
Three adjustments are Ι2C-Bus programmable: PHACOM = 0, 1/4, 1/8.

Digital Color Transient Improvement (DCTI)
A new digital algorithm is implemented to improve horizontal transitions of the
chrominance signals resulting in a better picture sharpness. A slow change from one
color to another by reason of small chrominance bandwidth is replaced by a steep
transition.
The exact position of a color transition (POS) is calculated by detecting the
corresponding zero transition of the second derivative of both chrominance signals. Low
pass filtering (LPU, LPV, LPUV) is performed to avoid noise sensitivity. The width of a
transition is derived from a threshold detector signal. It indicates an area around the
detected position where the first derivatives of the chrominance signals exceed a
programmable threshold (Ι2C signal: THRESH). The parameter THRESH modifies the
sensitivity of the DCTI-circuit. High values cause that only significant color transitions are
improved. Small color variations remain unchanged. The detected transition width can
be limited by the programmable parameter TRAWID. This parameter performs an
adaption to the input chrominance band width. For signals with small chrominance
bandwidth (e.g. video recorders) the DCTI-performance is optimized using high values
for TRAWID. Input signals with high chrominance bandwidth should be processed with
small values for TRAWID. If standard 4:1:1 video signals are processed, it is
recommended to choose values of the mid range for both parameters THRESH and
TRAWID.

Picture Manipulations
A graphic display effect is realized by programmable reduction of amplitude resolution
(Ι2C signals: YGR, YGRRES, CGR, CGRRES). A resolution of 1 to 4 bits is available. A
special characteristic avoids a reduction of picture brightness and color saturation.
The inverted display mode is attained by a programmable bit inversion for each signal
component (Ι2C signals: YINV, UINV, VINV).
Multiple combinations of both manipulations supply very amazing effects on the display.

16:9-Operation, Signal Compander
The compander enables a display with correct geometric proportions of 4:3 signals on
16:9-screens or 16:9-signals on 4:3-screens. A full screen display of 4:3-letterbox
signals on 16:9-screens is also practicable. Having a full screen display of such signals
on 4:3-screens only a part of the picture can be shown. In this operation mode a
horizontal shift of the picture part used for display is programmable (Ι2C signal: READD).
Expansion in vertical direction must be realized by manipulation of the vertical deflection
current.
To satisfy all these demands a horizontal compression or expansion of the video signals
is performed by raising or reducing the sample frequency. The data are written into a
memory using the system clock CLL and read with a clock of higher or lower frequency.

SDA 9280 B22
This realization does not effect the horizontal detail resolution of the picture because no
filtering is executed.
The highest read frequency is 4/3 of the CLL-frequency for signal compression, the
lowest is 3/4 of the CLL-frequency for signal expansion. The reading clock is supplied by
the internal PLL.
The compander operation mode is programmable via Ι2C signals COMP and COMEX.
Note: Positioning of a 4:3-signal on a 16:9-screen is realized by delaying the HS-signal.
HS also controls the deflection circuit. In the Siemens MEGAVISION® System a
programmable HS-delay is available in the Memory Sync Controller (MSC) circuit.

Frequency Response of Interpolator 2
(ƒs is the sampling frequency at the output of the interpolation filter)
In general D/A conversion requires postfiltering to avoid non-harmonic distortions
caused by intermodulations of the signal with its spectral images. These
intermodulations may come from non-linear characteristics of subsequent amplifier
stages or of the display. The spectral images are duplicates of the signal spectrum
around multiples of the sampling frequency. These images, a counterpart of aliasing in
the A/D conversion, become visible after D/A conversion. They are only reduced by the
sinx/x characteristic of the D/A converter.
Semiconductor Group
16
1998-02-01
SDA 9280 B22
An example of such non-harmonic distortions are periodic stripes with a frequency of
900 kHz appearing in a 4.8 MHz test pattern which is sampled with 13.5 MHz clock
frequency (2 * 4.8 MHz – (13.5 – 4.8) MHz = 900 kHz).
The ideal postfiltering comprises an ideal lowpass filter with an edge frequency at the
maximum signal frequency and a stop band rejection of at least 30 or 40 dB. In practice
the postfilter can be greatly simplified when a large transition band is allowed. For this
purpose a digital interpolator is implemented with a steep transition at the half of the
sampling frequency and an out of band rejection of more than 30 dB before
D/A conversion. Combined with a two-fold oversampling the first image appears around
twice the sampling frequency, thus leaving considerably more space for the transition
band of an analog postfilter. There is another good reason for using a digital
interpolation. Since the output frequency may vary with different compression or
expansion factors an analog filter with varying edge frequencies is necessary. This
requirement can only be fulfilled in the digital domain because the edge frequency is
linearly controlled by the sample frequency.
The amplification factor of the implemented interpolation filter is 65/64. The maximal
output clock frequency is 8/3 times of the input sample frequency. The diagram
(figure 6) shows the frequency response.
Oversampling can be switched off (Ι2C signal: OVSAMP). Then the 4:4:4 format is
directly D/A converted. With activated oversampling it is possible to switch off
oversampling filtering (Ι2C signal: OVFILT). In this operation mode the input clock
frequency is doubled but each sample is simply repeated twice.
2.8
Insertion Facilities
Three different values are inserted into the video signal: black level, a colored
background area and an arbitrary colored pattern.
The blanking interval of the input signal is not processed by the compander. Therefore
the black level shifting in the luminance signal, caused by the peaking filter (coefficient
LCOF) and the amplification factor of the oversampling filter, has to be restored by
inserting the correct value (BLACK). BLACK is programmable and must be computed
according to the coding of the input data using the following formulas:
BLACK = 128 + 65/128 * LCOF * (BLACKIN – 128)
BLACK = 128 + 65/128 * LCOF * BLACKIN
for positive dual coding
for 2’s complement
BLACKIN is the black level of the input signal, LCOF is the Lowpass coefficient of the
Luminance Peaking Filter: 0 ... [1/4] ... 1.5, 2
Black level insertion is controlled by the external signal HS. This signal also controls the
deflection circuit, consequently it has a stable phase referring to the horizontal blanking
interval. The value BLACK is inserted during 80 clock periods of the clock CLL. In the
Siemens MEGAVISION® System HS is supplied by the MSC-circuit. To adjust the right
insertion phase a programmable delay of HS is available (Ι2C signal: HSDEL).

The second insertion facility produces a colored background area on the display
controlled by Ι2C Bus. Activating this insertion mode (Ι2C signal: BACKGR) parts of the
display area are covered with a constant color (Ι2C signals: COLBY, COLBU, COLBV).
Starting at a programmable pixel position of each line (Ι2C signal: BCKPOS) the
following part is covered with the background values. The width of the insertion is also
programmable (Ι2C signal: BCKWID). To realize for example two vertical background
stripes at the left and right side of the display BCKPOS should be set to a high value.
Then the background color is inserted over the blanking interval (except the black level
phases) up to the first active pixels of the following line fixed by BCKWID. An example
for application is the display of a 4:3-picture on a 16:9-screen. The free parts of the
display and also the noisy start and end of the picture can be filled with background color.
An opening and closing curtain can also be realized using background insertion mode.
Insertion of an arbitrary pattern is controlled by the external signal INS. The color of the
pattern is programmable (Ι2C signals: COLFY, COLFU, COLFV). The insertion raster
corresponds to the 4:4:4 format. A fixed phase to the video signal is guaranteed by
processing the INS-signal by the compander. Using this insertion mode a colored
framing for multi-picture mode can be realized. The MSC of the Siemens MEGAVISION®
System supplies a suited signal (FRM). A connection of the BLN2-signal supplied by the
MSC to the INS-input enables a complete blanking of the horizontal and vertical inactive
parts of the video signal.
The polarity of the INS-signal is programmable by Ι2C Bus (INSNEG).
All insertions are performed after oversampling resulting in sharp transitions without
overshooting.
2.9
Amplification, D/A Conversion
Before D/A conversion a fine adjustment of the phase of the luminance signal is
performed (Ι2C signal: YDEL2). The delay of the luminance signal can be varied by one
period of the D/A converter clock.
The amplification factors of each signal component can be reduced by a factor of 0.5
(Ι2C signals: AMPY, AMPU, AMPV). This reduction of nominal amplification reserves
one bit for D/A conversion of overshooting, resulting from strong peaking or interpolation
filtering. The input amplitude resolution of 8 Bit is not reduced. For conversion of signals
without or with only small overshooting a reduction of the amplification factor is not
necessary. A digital limiter circuit prevent the D/A converters from possible overdriving
by clipping.
Note: Clipping causes a non-linear deformation with interferences between multiples of
the signal frequency and the sample rate of the signal and should be avoided by
reducing the amplification factor.
A triple 9 Bit D/A converter is implemented on the SDA 9280. The DACs are short circuit
protected converters with current outputs.

The Full Range Output Current of the Y, U, and V channels (IOFR) is determined by the
current IREF at the RREF pin by
IOFR ≅ (4/3) IREF
The voltage at pin RREF is generated via pin VREF by an internal operational amplifier and
follows the voltage at pin VREF. Thus IREF is given by
IREF ≅ VVREF/RREF
where RREF is a resistor between pin RREF and analog ground. Another way to define IREF
is the application of a current sink at the RREF point. For recommended values of VVREF
and IREF see chapter ’Recommended Operation Conditions’. For applications with lower
requirements there is still another way to define IOFR: Connect pin VREF to the positive
supply and apply a resistor against ground. Since in this operation mode the internal
reference amplifier goes into saturation, the exact value of IREF is not so well predictable

The internal PLL supplies the clock signals needed for compander operation, output
processing and D/A conversion. The output frequency of the PLL is defined by
programming the divider factors of the reference clock and of the VCO clock
(Ι2C signals: DIVREF, DIVVCO). The PLL always supplies the frequency needed for
oversampling. The clocks used in the other output processing parts are derived from this
oversampling clock. Even if no oversampling is programmed (OVSAMP = 0) DIVREF

and DIVVCO must be set according to the respective oversampling frequency. The
reference clock of the PLL is the system clock CLL. The output frequency of the PLL
fOUTPUT is calculated by the following equation:
fOUTPUT = fREFERENCE * (2 * DIVVCO) / DIVREF
Note: An arbitrary setting of the output frequency is not allowed. It has to be observed
that there is resulting an integer number of clock periods per line. E.g. the input
signal has 858 clock periods per line, 3:4 signal expansion results in
858 * 3/4 = 643.5 clock periods per line, which is not an integer number.
Therefore this adjustment results in phase jumps of the output clock and in an
unstable working condition of the PLL.
The following table gives an overview of possible PLL modes referred to an input signal
with 864 pixels per line and a clock frequency of 13.5 MHz.
