THEORY OF OPERATION
6.1
General
The STV9556 is a three-channel video amplifier supplied by a low supply voltage: V
CC
(typ.12V) and a
high supply voltage: V
DD
(up to 115V).
The high values of V
DD
supplying the amplifier output stage allow direct control of the CRT cathodes (DC
coupling mode).
In DC coupling mode, the application schematic is very simple and only a few external components are
needed to drive the cathodes. In particular, there is no need of the DC-restore circuitry which is used in
classical AC coupling applications.
The output voltage range is wide enough (
Figure 2
) to provide simultaneously :
Cut-off adjustment (typ. 25V)
Video contrast (typ. up to 40V),
Brightness (with the remaining voltage range).
In normal operation, the output video signal must remain inside the linear region whatever the cut-off,
brightness and contrast adjustments are.

Output voltage
A very simplified schematic of each STV9556 channel is shown in

The feedback network of each channel is integrated with a typical built-in voltage gain of G=20 (40k/2k).

POWER DISSIPATION
The total power dissipation is the sum of the static DC and the dynamic dissipation:
P
TOT
= P
STAT
+ P
DYN
.
The static
DC power dissipation is approximately:
P
STAT
= V
DD
x I
DD
+ V
CC
x I
CC
The dynamic dissipation is, in the worst case (1 pixel On/ 1 pixel Off pattern):
P
DYN
= 3 V
DD
x C
L
x V
OUT(PP)
x f x K (see
Note 6
)
where f is the video frequency and K the ratio between the active line and the total horizontal line duration.
Example:
for V
DD
= 110V, V
CC
= 12V,
I
DD
= 25mA, I
CC
= 60mA,
V
OUT
= 40 V
PP
, f = 40MHz,
C
L
= 8pF and K = 0.72.
We have:
P
STAT
= 3.47W and P
DYN
= 3.04W
Therefore:
P
TOT
= 6.51W.
Note 6: This worst thermal case must only be considered for TJmax calculation. Nevertheless, during the average life
of the circuit, the conditions are closer to the white picture conditions.

10 APPLICATION HINTS
10.1
How to choose the high supply voltage value (V
DD
) in DC coupling mode
The V
DD
high supply voltage must be chosen carefully. It must be high enough to provide the necessary
video adjustment but set to minimum value to avoid unecessary power dissipation.
Example (see
Figure 2
):
The following example shows how the optimum V
DD
voltage value is determined:
Cut-off adjustment range (B) : 25V
Max contrast (D) : 40V
Case 1:
10V Brightness (C) adjusted by the preamplifier :
V
DD
= A + B + C + D + E
V
DD
= 15V + 25V + 10V + 40V + 17V = 107V
Case 2:
10V Brightness (C) adjusted by the G1 anode:
V
DD
= A + B + D + E
V
DD
= 15V + 25V + 40V + 17V = 97V
10.2
Arcing Protection: schematics
As the amplifier outputs are connected to the CRT cathodes, special attention must be given to protect
them against possible arcing inside the CRT.
Protection must be considered when starting the design of the video CRT board. It should always be
implemented before starting to adjust the dynamic video response of the system.
The arcing network that we recommend (see
Figure 16
) provides efficient protection without deteriorating
the amplifier video performances.
The total resistance between the amplifier and the CRT cathode (R10+R11) protects the device against
overvoltages. We recommend to use R10+R11 > 200
.
Spark gaps are strongly recommended for arcing protection.
STV9556
13/24
Figure 16. Arcing protection network (one channel)
10.3
Arcing protection: layout and decoupling
Several layout precautions have to be considered to get the optimum arcing protection:
Sparkgap grounding: when an arc occurs, the energy must flow through the CRT ground without
reaching the amplifier. This is obtained by connecting the sparkgap grounding (point B) to the CRT
ground (socket) via a wide/short trace. Conversely the point B must be connected to the amplifier
ground via a longer/narrower trace.
Grounding separation: In order to set apart the amplifer ground and CRT ground, the R29/C29 net-
work (
Figure 16
) can be used.
Amplifier grounding: The 3 grounds GNDS, GNDA and GNDP must be connected together as
close as possible to the device.

Video response optimization: schematics in DC-coupling mode
The dynamic video response is optimized by carefully designing the supply decoupling of the video board
(see Section 10.7), the tracks (see Section 10.7), then by adjusting the input/output component network
(see Section 10.5).
For dynamic measurements such as rise/fall time and bandwidth, a 8pF load is used (total load including
the parasitic capacitance of the PC board and CRT Socket).
When used in kit with the STV921x preamplifier from ST, the preamplifier bandwidth register (BW, register
13) must be set to minimum (o dec) for an application with t

>5.5ns.

Video response optimization: outputs networks
The output network (R10/L1/R11) is used to adjust the amplifier video performances. Once R10 and R11
resistors are set to protect the application against arcing (R10 + R11>200
), it is possible to increase the
bandwidth by increasing L1.
10.6
Video response optimization: inputs networks
The input network also plays an important role in the device dynamic behaviour. We recommend to use
the reference input network #1, which is described in
Figure 17
, but 2 other networks (#2 and #3) can be
used to better match the required performances and the video board layout. Refer to the application note
referenced AN1510 for the complete description of these input networks.
10.7
Video response optimization: layout and decoupling
The decoupling of V
CC
and V
DD
through good quality HF capacitors (respectively C10 and C12) close to
the device is necessary to improve the dynamic performance of the video signal.
Careful attention has to be given to the three output channels of the amplifier.
Capacitor: The parasitic capacitive load on the amplifier outputs must be as small as possible.
Figure 9
from
Section 8
clearly shows the deterioration of the
t
R
/
t
F
when the capacitive load
increases. Reducing this capacitive load is achieved by moving away the output tracks from the other
tracks (especially ground) and by using thin tracks (<0.5mm), see
Figure 17
.
Cross talk: Output and input tracks must be set apart. The STV9556 pin-out allows the easy separa-
tion of input and output tracks on opposite sides of the amplifier (see
Figure 21
).
Length: Connection between amplifier output and cathode must be as short and direct as possible.

AC - Coupling mode
The STV9556 can be used in AC-Coupling mode in kit with the TDA9207/9212 preamplifier from ST. As
for the DC-coupling mode, the STV9556 drives perfectly the video signal in PICTURE BOOST conditions.
A typical schematic is given on the
Figure 18
below.
Figure 18. Video response optimization for one channel - AC coupling application
The advantage of such an architecture is to use smaller V
DD
and therefore to have smaller power
consumption. This is due to the fact that the STV9556 provides only the video signal and not the cut-off
adjustment. The disadvantage is to have an application with more components (DC restore circuitry).
Note that it is mandatory to keep the output video signal (point C) inside the linear area of the amplifier
(from 17V to V
DD
- 15V).

Stand-by mode, spot suppression
The usual way to set a monitor in stand-by mode is to switch-off the Vcc (12V).
The STV9556 has an extremely low power consumption (I
DDS
= 60A when V
CC
<1.5V) in stand-by mode
and the outputs are set to low level (white picture).
To avoid the display of a spot effect during the switch-off phase, it is necessary to adjust the G1 circuitry
(Resistors Rx and Cx, see
Figure 19
) to pull the G1 voltage to low value for a long enough period of time.

10.10 Conclusion
Video response is always a compromise between several parameters. For example, the rise/fall time
improvement leads to the overshoot deterioration.
The recommended way to optimize the video response is:
1
To set R10+R11 for arcing protection (min. 200
)
2. To adjust R20 and R10+R11.
Increasing their value increases the
t
R
/
t
F
values and decrease the overshoot
3. To adjust L1
Increasing L1 speeds up the device but increases the overshoot.
4. To adjust the input network for the final dynamic tunning (e.g.: critical damping)
We recommend our customers to use the schematic shown on
Figure 23
as a starting point for the video
board and then to apply the optimization they need.
