DESCRIPTION
The TDA9110 is a monolithic integrated circuit assembled in 32-pin shrunk dual in line plastic package. This IC controls all the functions related to the
horizontal and vertical deflection in multimode or
multi-frequency computer display monitors.
The internal synchro processor, combined with the
very powerful geometry correction block make the
TDA9110 suitable for very high performance monitors with very few external components.
The horizontal jitter level is extremely low. (Typical
standard deviation : 300ps @ 31kHz).
It is particularly well suited for high-end 15” and 17”
monitors.

OPERATING DESCRIPTION
I - GENERAL CONSIDERATIONS
I.1 - Power Supply
The typical values of the power supply voltages
VCC and VDD are 12V and 5V respectively. Perfect
operation is obtained for VCC between 10.8 and
13.2V and VDD between 4.5 and 5.5V.
In order to avoid erratic operation of the circuit
during transient phase of VCC switching on, or off,
the value of VCC is monitored and the outputs of
the circuit are inhibited if VCC is less than 7.5V
typically.
Similarly,VDD is monitored and internally set-up
until VDD reaches 4V (see I 2C Control Table for
power on reset).
In order to have a verygood powersupply rejection,
the circuit is internally supplied by several voltage
references(typical value : 8V).Two of thesevoltage
references are externally accessible, one for the
vertical and one for the horizontal part. If needed,
these voltage references can be used (if ILOAD is
less than 5mA). It is necessary to filter the a.m.
voltage references by external capacitors connected to ground, in order to minimize the noise
and consequently the ”jitter” on vertical and horizontal output signals.
I.2 - I2C Control
TDA9110 belongs to the I2C controlled device family. Instead of being controlled by DC voltages on
dedicated control pins, each adjustment can be
done via the I2C Interface.
The I2C bus is a serial bus with a clock and a data
input. Thegeneral functionand thebus protocolare
specified in the Philips-bus data sheets.
The interface (Data and Clock) is TTL-level compatible. The internal threshold level of the input
comparator is 2.2V (when VDD is 5V). Spikes (up
to 50ns) are filtered by an integrator and the clock
speed is limited to 400kHz.
The data line (SDA) can be used bidirectionally(i.e.
in read-mode the IC clocks out a reply information
(1 byte) to the micro-processor).
The bus protocol prescribes always a full-byte
transmission. The first byte after the start condition
is used to transmit the IC-address(7 bits-8C) and
the read/write bit (0 write - 1 read).
I.3 - Write Mode
In write mode the second byte sent contains the
subaddress of the selected function to adjust (or
controlsto affect)and the third byte the corresponding data byte.It is possible to send more than one
data byte to the IC. If after the third byte no stop or
start condition is detected, the circuit increments
automaticallyby one the momentary subaddressin
the subaddress counter (auto-increment mode).
So it is possible to transmit immediately the next
data bytes without sending the IC address or
subaddress.It can be useful to reinitialize the whole
controls very quickly (flash manner). This procedure can be finished by a stop condition.
The circuit has 16 adjustment capabilities : 2 for the
Horizontal part, 4 for the Vertical, 2 for the E/W
correction, 2 for the Dynamic Horizontal phase
control,2 for the Moire options, 3 for the Horizontal
and Vertical Dynamic Focus and 1 for the HSize
amplitude control.
15 bits are also dedicated to several controls
(ON/OFF, Synchro Priority, Detection Refresh and
Xray reset).
I.4 - Read Mode
During the read mode the second byte transmits
the reply information.
The reply byte contains the Horizontal and Vertical
Lock/Unlock status, the Xray activation status and,
the Horizontaland Vertical polarity detection.It also
contains the Synchro detection status which is
used by the MCU to assign the Synchro priority.
A stop conditionalways stops all the activities of the
bus decoder and switches to high impedance both
for the data and the clock line (SDA and SCL).
See I2C Subaddress and control tables.
I.5 - Synchro Processor
TheinternalSynchroProcessor allowsthe TDA9110
to accept any kind of input synchro signals :
- separated Horizontal & Vertical TTL-compatible
synchro signals,
- composite Horizontal &Vertical TTL-compatible
synchro signals.
I.6 - Synchro Identification Status
The MCU can choose via the I2C the synchro
priority thanks to the system identification status
provided by the TDA9110. The extracted Vertical
synchro pulse is available when this identification
status has been received and when the 12V is
supplied. Even in Power managementmode the IC
is able to inform the MCU that synchrosignals were
detected due to its 5V supply. We recommend to
use the device as following : first, refresh the synchro detection by I2C, then check the status of H/V
det and Vdet by I2C read.
Sync priority choice should be :

OPERATING DESCRIPTION (continued)
Of course, when the choice is done, we can refresh
the synchro detectionsand verify that the extracted
Vsync is present and that no synchro type change
have occured.
Synchro processor is also giving synchro polarity
information.
Figure 7
I.7 - IC status
TheIC can inform the MCUabout the 1st Horizontal
PLL or Vertical section status (locked or not), and
about the Xray protection (activated or not).
Resettingthe Xray internal latch can be done either
by decreasing the VCC supply or directly resetting
via the I2C interface.
The last feature performed is the removing of
equalizing pulses to avoid parasitic pulses on
phase comparator input (which is sensitive to
wrong or missing pulses).
TRAMEXT

II.2 - PLL1
The PLL1 consists of a phase comparator, an external filter and a voltage control oscillator (VCO).
The phase comparator is a ”phase frequency” type
designed in CMOS technology. This kind of phase
detector avoids locking on false frequencies. It is
followed by a ”charge pump”, composed of two
current sources sunk and sourced(Typically I = 1mA
when locked and I = 140µA when unlocked). This
difference between lock/unlock permits a smooth
catching of the horizontal frequency by the PLL1.
This effect is reinforced by an internal original slow
down system when the PLL1 is locked, avoiding the
Horizontal frequency to change too fast.
The dynamic behaviour of the PLL1 is fixed by an
external filter which integrates the current of the
charge pump. A ”CRC” filter is generally used (see
Figure 8).
I.8 - Synchro Inputs
Both H/HVin and Vsyncin inputs are TTL compatible triggers with Hysterisis to avoid erratic detection. It includes pull up resistor to VDD.
I.9 - Synchro Processor Output
The synchro processor delivers the Hlockout signal
on a TTL-compatible CMOS output.
Hlockout is the Horizontal 1st PLL status (5V when
locked). It allows the MCU to check the Horizontal
IC locking.
II - HORIZONTAL PART
II.1 - Internal Input Conditions
A digital signal (Horizontal synchro pulse or TTL
composite) is sent by the synchro processor to the
horizontal part.
Positive or negative signal can be applied to the
Horizontal part input (see Figure 6).
Using internal integration, both signals are recognized if Z/T < 25%. Synchronization occurs on the
leading edge of the internal synchro signal. The
minimum value of Z is 0.7µs.

synchro (if any) to avoid taking in account missing

The VCO uses an external RC network. It delivers
a linear sawtooth obtained by the charge and the
discharge of the capacitor, with a current proportionnal to the current in the resistor. The typical
thresholds of the sawtooth are 1.6V and 6.4V.

The control voltage of the VCO is between 1.33V
and 6V (see Figure 10). The theorical frequency
range of this VCO is in the ratio of 1 to 4.5. The
effective frequency range has to be smaller (1 to
4.2) due to clamp intervention on filter lowest value.
In order to increase this effective frequency range,
to a possiblerange of 1 to6.0 one canadda resistor
from Pin 6 to Href leading.
The synchro frequency must always be higher than
the free running frequency. For example, when
using a synchro range between 31kHz and 96kHz,
the suggested free running frequency is 25kHz.
The PLL1 ensures the coincidence between the
leading edge of the synchro signal and a phase
reference obtained by comparison between the
sawtooth of the VCO and an internal DC voltage
2
which is I C adjustable between 2.65V and 3.75V
(corresponding to ± 10%) (see Figure 11).

The TDA9110 also includes a Lock/Unlock identification block which senses in real time whether the
the PLL1 is locked or not on the incominghorizontal
synchro signal. The resulting information is available on Hlockout (see Synchro Processor). The
block function is described in Figure 12.
The NOR1 gate receive the phase comparator
output pulses (which also drive the charge pump).
When the PLL1 is locked, we have on point A a very
small negative pulse (about 100ns) at each horizontal cycle, so after the RC filter, there is a high
level on Pin 14 which forces Hlockout to high level.
The hysterisis comparator detects locking when
Pin 14 reachs 6.5V and unlocking when Pin 14
decreases to 6.0V.
When the PLL1 is unlocked, the 100ns negative
pulse on Abecomes much larger and consequently
the average level on Pin 14 decreases. It forces
Hlockout to low level.
The Pin 14 status is approximately the following :
- near 0V when there is no H-Sync
- between 0 and 4V with H-Sync frequency different from VCO
- between 4 to 8 V when VCO frequency reaches
H-Sync one (but not already in phase)
- near 8V when PLL1 is locked.
It is important to notice that Pin 14 is not an
output pin but is only used for filtering purpose
(see Figure 12).
The lock/unlock information is also available
through the I2C read.
recommanded input current is 5mA (see Figure 14).
The duty cycle is adjustable through I2C from 30%
to 60%. For Start Up safe operation, the initial duty
cycle (afterPower on reset) is 60% in order to avoid
to have a too long conduction of the BU transistor.
Themaximumstoragetime isabout38% (TFLY/2.TH).
Typically, TFLY/TH is around 20% which means that
Ts max is around 28%.
II.3 - PLL2
The PLL2 ensures a constant position of the
shaped flyback signal in comparison with the sawtooth of the VCO (Figure 13).
The phase comparator of PLL2 (phase type comparator) is followed by a charge pump (typical
output current : 0.5mA).
The flyback input consists of an NPN transistor.
This input must be current driven. The maximum

OPERATING DESCRIPTION (continued)
Obviously the power scanning transistor cannot be
directly driven by the integrated circuit. An interface
has to be added between the circuit and the power
transistor either of bipolar or of MOS type.
II.4 - Output Section
The H-drive signal is sent to the output through a
shaping block ensuring Ts and H-drive duty cycle
(I2C adjustable) (see Figure 13). In order to secure
the scanning power part operation, the output is
inhibited in the following cases :
- when VCC is too low,
- when the Xray protection is activated,
- during the Horizontal flyback,
- when the HDrive I2C bit control is off.
The output stage consists of a NPN bipolar transistor. Only the collector is accessible(see Figure 15).
II.5 - X-RAY Protection
The X-Ray protection is activated by application of
a high level on the X-Ray input (8V on Pin 25). The
consequencies of X-Ray protection are :
- inhibition of H-Drive output
- activation of vertical blanking output.
This protection is reset either by VCC switch off or
by I2C (see Figure 16).
Figure 15
VCC
9110-32.EPS
26 H-DRIVE
The output NPN is in off-state when the power
scanning transistor is also in off-state.
The maximum output current is 30mA, and the
corresponding voltage drop of the output VCEsat is
0.4V typically.
II.6 - Horizontal and Vertical Dynamic Focus
The TDA9110 delivers a horizontalparabola which
is added on a vertical parabola waveform on Pin
15. This horizontal parabola comes from a sawtooth. The phase advance versus Horizontal flyback middle is kept constant for each frequency
(about 860ns). This sawtooth is present on Pin 16
where the horizontal focus capacitor is the same
as C0 to obtain a controlled amplitude (from 2 to
4.7V typically).
Symmetry (keystone) and amplitude areI 2C adjustable (see Figure 17). The Vertical dynamic focus is
tracked with VPOSand VAMP.Its amplitudecan be
adjusted. It is also affected by S and C corrections.
This positive signal has to be connectedto the CRT
focusing grids.

II.7 - Moire Output
The moire output is intented to correct a beat
between the horizontal video pixel period and the
current CRT pixel width.
The moire signal is a combination of the Horizontal
and the Vertical frequency signals.
To achieve a moire cancellation, the moire output
has to be connected to any point of the chassis
controlling the horizontal position. We recommend
to introduce this “ Horizontal Controlled Jitter” on
20/29
the relative ground of PLL2 capacitor where this
“controlled jitter” frequency type will directly affect
the horizontal position.
The amplitude of the signal is I2C adjustable.
If the H-Moire feature is not necessary in the application, the H-Moire output (Pin 3) can be used as
a 5 bits DAC output (0.3V to 2.2V). If the H-Moire
output is not used at all, so the Pin 3 must be either
kept to high impedance or grounded via a resistor.

OPERATING DESCRIPTION (continued)
III - VERTICAL PART
III.1 - Geometric Corrections
The principle is represented on Figure 20.
Starting from the vertical ramp, a parabola shaped
current is generated for E/W correction, dynamic
horizontal phase control correction, and vertical
dynamic Focus correction.
The parabola generator is made by an analog
multiplier, the output current of which is equal to :
∆I = k ⋅ (VOUT - VDCOUT)2
where Vout is the vertical output ramp (typically
between 2 and 5V) and Vdcout is the vertical DC
output adjustable in the range 3.2V to 3.8V which
generate a dissymetric parabola if needed (keystone adjustment).
In order to keep a good screen geometry for any
end user preferencesadjustment,we implemented
the ”geometry tracking”.
Due to large output stages voltage range (E/W,
FOCUS), the combination of tracking function with
maximum vertical amplitude max or min vertical
position and maximum gain on the DAC control
may lead to the output stages saturation. This must
be avoided by limiting the output voltage with apropriate I2C registers values.
For the E/Wpart and the Dynamic Horizontalphase
control part, a sawtooth shaped differential current
in the following form is generated:
∆I’ = k’ ⋅ (VOUT - VDCOUT)
Then ∆I and ∆I’ are addedand converted into voltage for the E/W part.
Each of the two E/W components or the two Dynamic Horizontal phase control ones may be inhibited by their own I2C select bit.
The E/W parabola is available on Pin 24 via an
emitter follower which has to be biased by an
external resistor (10kΩ). It can be DC coupled with
external circuitry.
The Vertical Dynamic Focus is combined with the
Horizontal one on Pin 15.
The dynamic Horizontalphasecontrol current drives
internally the H-position, moving the Hfly position on
the Horizontal sawtooth in the range of ± 1.4% TH
both on SidePin Balance and Parallelogram.

III.3 - DC HSize Output Control
A 7 bits D/A converter is available on Pin 28. The
output is a NPN transistor emitter follower output
with an internal 100mA current source from output
to ground (max. sunk current). The Max. current
the output is able to source is 2.5mA. The output
level is between 0.5V to 4.5V. This DAC can be
used to control the H-Size.

III.5 - Function
When the synchronization pulse is not present, an
internal current source sets the free running frequency. For an external capacitor, COSC = 150nF,
the typical free running frequency is 106Hz.
The typical free running frequency can be calculated by :
1
f0 (Hz) = 1.6 e−5 ⋅
COSC
A negative or positive TTL level pulse applied on
Pin 2 (VSYNC)as well as a TTLcomposite synchro
on Pin 1 can synchronize the ramp in the range
[fmin , fmax]. This frequency range depends on the
external capacitorconnectedon Pin 22.A capacitor
in the range [150nF, 220nF] ± 5% is recommanded
forapplicationin thefollowingrange: 50Hz to 120Hz.
9110-38.EPS
V_FOCUS
TDA9110
OPERATING DESCRIPTION (continued)
Typical maximum and minimum frequency, at 25oC
and without any correction (S correction or C correction), can be calculated by :
f(Max.) = 2.5 x f0 and f(Min.) = 0.33 x f0
If S or C corrections are applied, these values are
slighty affected.
If a synchronization pulse is applied, the internal
oscillator is automaticaly caught but the amplitude
is no more constant. An internal correction is activated to adjust it in less than a half a second : the
highest voltage of the ramp Pin 22 is sampled on
the sampling capacitor connected on Pin 20 at
each clock pulse and a transconductanceamplifier
generates the charge current of the capacitor. The
ramp amplitude becomes again constant.
The read status register enables to have the vertical Lock-Unlock and the vertical Synchro Polarity
informations.
We recommand to use a AGC capacitor with low
leakage current. A value lower than 100nA is mandatory.
A good stability of the internal closed loop is
reached by a 470nF ± 5% capacitor value on
Pin 20 (VAGC).
III.6 - I2C Control Adjustments
Then, S and C correction shapes can be added to
this ramp. These frequence independent S and C
corrections are generated internally. Their amplitudes are adjustable by their respective I2C register. They can also be inhibited by their Select bit.
Finally, the amplitude of this S and C corrected
ramp can be adjusted by the vertical ramp amplitude control register.
The adjusted ramp is available on Pin 23 (VOUT) to
drive an external power stage.
The gain of this stage is typically 25% depending
on its register value.
The DC value of this ramp is driven by its own I2C
r eg is t e r (ve rtic a l P o sit ion ). I ts v a lue is
VCDOUT = 7/16 ⋅ VREF ± 300mV.
The VDCOUT voltage is correlated with DC value of
VOUT. It increases the accuracy when temperature
varies.
By using the vertical moire, VDCOUT can be modulated from frame to frame. This function is intended
to correct slightly the vertical video line to line
period from actual CRT line to line width.
III.7 - Basic Equations
In first approximation,the amplitude of the ramp on
Pin 23 (Vout) is :
VOUT - VMID = (VOSC - VMID) ⋅ (1 + 0.25 (VAMP))
with VMID = 7/16 ⋅ VREF ; typically 3.5V, the middle
value of the ramp on Pin 22
VOSC = V22 , ramp with fixed amplitude
VAMP is -1 for minimum vertical amplitude register
value and +1 for maximum
On VDCOUT, the voltage (in volts) is calculated by :
VDCOUT = VMID + 0.3 (VPOS)
with VPOS equals -1 for minimum vertical position
register value and +1 for maximum
The current available on Pin 22 is :
3
IOSC = ⋅ VREF ⋅ COSC ⋅ f
8
with COSC : capacitor connected on Pin 22
f : synchronization frequency
