FUNCTIONAL DESCRIPTION
1 - DEFLECTION CIRCUIT
Note : [X,Y] : line number referred to the internal
line counter numbering
- Fully integrated synch. separator, with a low pass
filter, a black level alignment of the Y/CVBS input,
a slicing level at 2/3,1/3 of the sync. pulse amplitude.
- Frame sync. pulse locked on 2 fH frequency to
perfect interlace.
- 500kHz VCO with an external ceramic resonator.
- Two phase locked loops
• the first PLL locks the VCO on the video signal
frequency,
• the second PLL compensates the line transistor
storage time.
- Three time constants for the first PLL.
• the long time constant is used for normal operation
• the short time constant is automatically used
during the frame retrace and in search mode of
VCR when the frame pulse is outside [258,264]
and [309,314].
• very long time constant when no video recognition
Time constants in normal operation
(automatic selection of time constants) :
50Hz input signal :
- short time constant : [306, 21]
- long time constant : the rest of the field
60Hz input signal :
- short time constant : [0, 16]
- long time constant : the rest of the field
• inhibition of the first PLL :
the first locked loop is opened from line 309 to
line 4.5 (or 314) in 50Hz mode. It is opened from
line 258 to line 5.5 (or 264) in 60Hz mode.
• the time constants values are chosen by means
of external components.
• possibility to force the short time constant
through the bus.
• possibility to force the very long time constant
through the bus.
- Video identification : coincidence detector between the line synchro top and a line frequency
window from the first PLL. The video identification
2
status is available in the output register of the I C
bus decoder.
- Generation of burst gate pulses and line frequency signals from the first PLL to drive the
chroma and video circuits. The burst gate pulse
is also sent to the sandcastle generator.
- Frame synchro window :
[248, 352]
catching
- Field frequency selection windows :
[248, 288]
60 Hz mode selec tion if two
consecutive frame pulses occur
inside this window,otherwise 50Hz
mode selection.
[288, 352]
50Hz mode selection window
- frame blanking pulse :
from line 0 to 21 in 50Hz mode
from line 0 to 16 in 60Hz mode
- Vertical output pulse is 10.5 lines long.
- Horizontal output pulse : 28µs line pulse on an
open collector output;
- Start up circuit : the horizontal output is at a high
level when VCC increases from 0 to 6.8V. On
shutting down, horizontal pulses are disabled
when VCC is below 6.2V.
- Soft-start circuit : the duty cycle of the horizontal
output is 78 % (Thigh/(Thigh + TLow)) when VCC1
is lower than (0.75 x VCC2 ), during the rising
time.
During the falling time, a 78% duty cycle HOUT
pulse is provided when VCC1 is lower than
(0.60 x VCC2).
- Possibility to disable the horizontal output pulse
through the bus (force a high level on HOUT).
- Horizontal position adjustment controlled by bus.
- Bus controlled output voltage to adjust the vertical
amplitude; this voltage permits to adjust the slope
of the vertical sawtooth generated by the external
frame booster.
- Bus controlled vertical position ; the high level of
the vertical pulse permits to adjust the vertical
position.
- Bus controlled 4/3-16/9 selection : the low level
of the vertical pulse is 0.1V when 16/9 is selected,
2V when 4/3 is selected.
- Combined flyback input and sandcastle output
(Pin 37).
Two thresholds on LFB/SCO Pin : The lowest
threshold (0.7V) permits to extract the line blanking pulse; the highest threshold (2V) permits to
extract the line pulse for PLL2.
The sandcastle signal at Pin 37 is used to control
the external baseband chroma delay line.

Center frequency : - 4.43MHz,
3.58MHz for PAL, NTSC
- 4.25MHz, for SECAM
(f-3dB = 3 MHz ; -2 0 dB
rejection between 4.1MHz
and 4.4MHz)
- Integrated chroma bandpass :
Q = 3.5
Center frequency : 4.43MHz, 3.58MHz
- Integrated cloche filter for SECAM :
Q = 16
Center frequency : 4.286MHz
- Integrated delay line :
Bandwidth = 8MHz
- Integrated low pass filter for deflection part.
- All filters are tuned with a reference phase locked
loop.
The PLL consists of a lowpass filter, a phase
comparator, a loop filter (an external capacitor).
The reference signal is the continuous carrier
wave from the VCO (4.43MHz or 3.58MHz). The
PLL adjusts the center frequency of the lowpass
so that it is equal to the reference signal. The
tuning voltage of the PLL is used to adjust all other
filters. The cloche filter is fine tuned with a second
PLL operating during frame retrace.

OSD insertion threshold is 0.7V.
Automatic cut-off current loop : 2V cut-off range.
Sequential cut-off current measurement during
the three lines after the frame blanking signal.

5 - OTHER FUNCTIONS : IF CONTROLS
5.1 - Volume Control and Mute
The volume control voltage range on Pin 10 is from
0.5V to 5V. A low voltage on Pin 10 (below 0.2V)
will mute the FM demodulator of the IF circuit
STV8224. It will put the volume at the minimum
level and thus there will be no sound either in TV
mode or SCART mode.
The volume control voltage and the mute level are
controlled by the bus.
5.2 - IF Standard and TV/SCART Mode Selection
The selection of IF standard (positive or negative
vision modulation) and theTV/SCART mode is controlled by the bus. The selection is converted in four
voltages on Pin 21.
The lowest voltage selects the TV mode and the
NEGATIVE vision modulation.
The highest voltage (open collector output with
internal pull-up resistor to VCC) selects the SCART
mode and the NEGATIVE vision modulation.
The two other intermediate voltages select either
TV mode and POSITIVE vision modulation or
SCART mode and POSITIVE vision modulation.

- STV2118B requires 2 XTALS (4.43MHz and 3.58MHz) for all operations (even with PAL and SECAM only signals).
This drawback will be improved in new coming versions.
- Recommended 4.43MHz XTAL is JAUCH Number 10080082.
