THEORY OF OPERATION
6.1
General
The STV9555 is a three-channel video amplifier supplied by a low supply voltage: VCC (typ.12V) and a
high supply voltage: VDD (up to 115V).
The high values of VDD 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).
)
s
t(
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 STV9555 channel is shown in Figure 3.
The feedback network of each channel is integrated with a typical built-in voltage gain of G=20 (40k/2k).
The output voltage VOUT is given by the following formula:
VOUT = (G+1) x VREF - (G x VIN)
for G = 20 and VREF = 5.6V, we have
VOUT = 117.6 - 20 x VIN

POWER DISSIPATION
The total power dissipation is the sum of the static DC and the dynamic dissipation:
PTOT = PSTAT + PDYN.
The static DC power dissipation is approximately:
PSTAT = (VDD x IDD )+ (VCC x ICC)
The dynamic dissipation is, in the worst case (1 pixel On/ 1 pixel Off pattern):
PDYN = 3 VDD x CL x VOUT(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 VDD = 110V, VCC = 12V,
IDD = 15mA, ICC = 40mA,
VOUT = 40 VPP, f = 35MHz,
CL = 8pF and K = 0.72.
c
u
d
We have:
PSTAT = 2.13 W and PDYN = 2.66 W

Therefore:
PTOT = 4.79W.

APPLICATION HINTS
10.1 How to choose the high supply voltage value (VDD) in DC coupling mode
The VDD 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 VDD voltage value is determined:
– Cut-off adjustment range (B) : 25V
– Max contrast (D) : 40V
Case 1:
10V Brightness (C) adjusted by the preamplifier :
VDD = A + B + C + D + E
VDD = 15V + 25V + 10V + 40V + 17V = 107V
Case 2:
c
u
d
10V Brightness (C) adjusted by the G1 anode:
VDD = A + B + D + E
VDD = 15V + 25V + 40V + 17V = 97V

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 Ω.

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.

10.4 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 R/tF>5.5ns.

10.5 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>200Ω), 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 VCC and VDD 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 tR/tF 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 STV9555 pin-out allows the easy separation of input and output tracks on opposite sides of the amplifier (see Figure 21).

10.8 AC - Coupling mode
The STV9555 can be used in AC-Coupling mode in kit with the TDA9207/9212 preamplifier from ST. As
for the DC-coupling mode, the STV9555 drives perfectly the video signal in PICTURE BOOST conditions.
A typical schematic is given on the Figure 18 below.

The advantage of such an architecture is to use smaller VDD and therefore to have smaller power
consumption. This is due to the fact that the STV9555 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 VDD - 15V).

10.9 Stand-by mode, spot suppression
The usual way to set a monitor in stand-by mode is to switch-off the Vcc (12V).
The STV9555 has an extremely low power consumption (I DDS = 60 µA when VCC<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 during a sufficient time duration.

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 Ω)
2. To adjust R20 and R10+R11.
Increasing their value increases the
tR/tF 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.
