DESCRIPTION
The TDA9210 is an I2C Bus controlled RGB pre-
amplifier designed for Monitor applications, able to
mix the RGB signals coming from any OSD de-
vice. The usual Contrast, Brightness, Drive and
Cut-Off Controls are provided.
In addition, it includes the following features:
– OSD contrast,
– Bandwidth adjustment,
– Grey background,
– Internal back porch clamping pulse generator.

(Plastic Package)
ORDER CODE: TDA9210
The RGB incoming signals are amplified and
shaped to drive any commonly used video amplifi-
ers without intermediate follower stages. Even
though encapsulated in a 24-pin package only,
this IC allows any kind of CRT Cathode coupling :
– AC coupling with DC restore,
– DC coupling with Feed-back from Cathodes,
– DC coupling with Cut-Off controls of the Video
amplifier (ST Amplifiers TDA9533/9530).
As for any ST Video pre-amplifier, the TDA9210 is
able to drive a real load without any external inter-
face.
One of the main advantages of ST devices is their
ability to sink and source currents while most of
the devices from our competitors have problems
to sink large currents.
These driving capabilities combined with an origi-
nal output stage structure suppress any static cur-
rent on the output pins and therefore reduce dra-
matically the power dissipation of the device.
Extensive integration combined with high perform-
ance and advanced features make the TDA9210
one of the best choice for any CRT Monitor in the
14” to 17” range.
Perfectly matched with the ST Video Amplifiers
TDA9535/36, these 2 products offer a complete
solution for high performance and cost-optimized
Video Board Application.

4.6 - Brightness Adjustment (8 bits)
Brightness adjustment is controlled by the I2C Bus
via Register 2. It consists of adding the same DC
voltage to the three RGB signals, after contrast ad-
justment. When the blanking pulse equals 0, the
DC voltage is set to a value which can be adjusted
between 0 and 2V with 8mV steps (see Figure 3).
The DC output level is forced to the ”Infra Black”
level (VDC) when the blanking pulse is equal to 1.
4.7 - Drive Adjustment (3 x 8 bits)
In order to adjust the white balance, the TDA9210
offers the possibility of adjusting separately the
overall gain of each channel thanks to the I2C bus
(Registers 3, 4 and 5).
The very large drive adjustment range (48 dB) al-
lows different standards or custom color tempera-
tures.
It can also be used to adjust the output voltages at
the optimum amplitude to drive the CRT drivers,
keeping the whole contrast control for the end-
user only.
The drive adjustment is located after the Contrast,
Brightness and OSD switch blocks, so it does not
affect the white balance setting when the BRT is
adjusted. It also operates on the OSD portion of
the signal.
4.8 - OSD Inputs
The TDA9210 allows to mix the OSD signals into
the RGB main picture. The four pins dedicated to
this function are the following:
– Three TTL RGB inputs (Pins 8, 9, 10) connected
to the three outputs of the corresponding OSD
processor.
– One TTL fast blanking input (Pin 11) also con-
nected to the FBLK output of the OSD processor.
When a high level is present on the FBLK, the IC
acts as follows:
– The three main picture RGB input signals (IN1,
IN2, IN3) are internally switched to the internal
input clamp reference voltage.
– The three output signals are set to the voltage
corresponding to the three OSD input logic
states (0 or 1). (See Figure 3).
If the OSD input is at low level, the output and
brightness voltages (VBRT) are equal.
If the OSD input is at high level, the output voltage
iasnVI2OCSDb,uws-hceornetrVoOlleSdDv=olVtaBgReT. + OSD and OSD is
OSD varies between 0 V to 4.9 V by 320 mV steps
via Register 7 (4 bits). The same variation is ap-
plied simultaneously to the three channels provid-
ing the OSD contrast.
The grey color can be obtained on output signals
when:
– OSD1 = 1, OSD2 = 0 and OSD3 = 1,
– A special bit (bit 5 or 6) in Register 9 is set to 1.
If R9b5 is set to 1, light grey is obtained on output.
If R9b6 is set to 1, dark grey is obtained on output.
In the case where R9b5 and R9b6 are set to 0, the
normal operation is provided on output signals.
4.9 - Output Stage
The overall waveforms of the output signal are
shown in Figure 3 and Figure 4. The three output
stages, which are large bandwidth output amplifi-
ers, are able to deliver up to 4.4 VPP for 0.7 VPP on
input.
When a high level is applied on the BLK input
(Pin 20), the three outputs are forced to ”Infra
Black” level (VDC) thanks to a sample and hold cir-
cuit (described below).
The black level (which is the output voltage out-
side the blanking pulse with minimum brightness
and no Video input signals) is 400 mV higher than
VDC.

by
The sample and hold circuit is used to control the
”Infra Black” level in the range of 0.5 V to 2.5 V via
Register 6 (in case of AC coupling) or Registers
10, 11, 12 (in case of DC coupling) .
This sampling occurs during an internal pulse
(OCL) generated inside the blanking pulse win-
dow.
