NX56 Chassis Signal Processing Introduction
Brief introduction
For different market requirements, our design it in two versions, one is
for Latin America, we call the chassis as NX56-LA, the another one is for
Asia Pacific Area, we call the chassis as NX56-AP. NX56-LA and
NX56-AP adopt different UOC, The UOC for Latin America have
CCD-Chip and BTSC function, so added AN5832SA to realize BTSC,
but the UOC for Asia Pacific region does not have the two functions but
SECAM system is necessary. NX56 Chassis not only match 21inches
CRT, but also match 25 and 29inches CRT. Due to different screen sizes,
maybe adopt different audio power amplifiers. The others should be the
same. No matter NX56-AP what NX56-LA, they are use same main PCB
board, just different peripheral components.

RF Section
Tuner Tu101 receive the radio frequency signal, after inside circuit to do
signal receiving, and signal amplifying. The amplified high frequency
signal accompany with the high frequency oscillation voltage oscillated
by set oscillator input to the mixer. The IF picture signal and sound signal
formed in mixer and output from mixer, then send to picture IF
processing circuit.

Vertical Scanning Section
Vertical scanning section adopted STV8172A vertical deflection booster, we use as
differential-output driver. The vertical raw-tooth wave signal sends out from pin14/15 of IC201
VDA/VDB. The two differential signal input pin 1 and 7 of STV8172A IC301. Pin2(+14v) and
Pin7(-14v) of IC301 is power supply which come from the main power transformer. Pin 6 is boost
voltage, rectified by D301. C309,C301 and R305 makes up a voltage feedback network, R306 is a
damping resistor. C306 is correction capacitor, R308 is current feedback resistor.

Versatile signal processor for CRT TV applications
Rev. 0.11 — 25 January 2007Product data sheet
1.General description
The UOC-TOP-64 series is a very flexible concept which offers attractive solutions for 1fH
TV receivers with CRTs. This new concept offers a complete range of products with the
right price level to cover TV receivers from basic mono 14 inch sets up to the best
featured large and/or wide screen AV-stereo TV sets. The UOC-TOP-64 concept can also
be used as front-end for 2f
The UOC-TOP-64 concept is mounted in a SDIP64 package and is split up in the following
ranges:
• AV-110 (AV-stereo) concept. It contains a video processor with many features and it
has an analog audio control circuit with balance, treble, bass and loudness control.
Two different micro processor are available for this concept, one with OSD and
Closed Captioning or Teletext and Closed Captioning features (UOCTOP_1PTXT
version), the other with (extended) OSD features (UOCTOP_OSD version). The block
diagram is given in Figure 1
• AV-90 concept. This concept is nearly identical to the AV-110 concept. The only
difference that it does not contain an East-West and Scan Velocity Modulation (SVM)
output. This concept is intended for 90× picture tubes.
• Mono-110 concept. The functional content of this concept is comparable with that of
the AV 110 concept, however, it has just stereo input switch and no audio control
circuit. The block diagram is given in Figure 1
• Mono-90 concept. This concept is intended for 90× picture tubes. The circuit has an
audio switch for mono signals but the mono inputs can also be used as a stereo input.
In this range most of the video and audio processing features have been omitted. Also
this concept can be supplied with one of the two micro processors (UOCTOP_1PTXT
or UOCTOP_OSD version). The block diagram is given in Figure 2
and LCD TV receivers.

The most important features of the complete IC series are given in the following feature
lists.
All packages are according to the ROHS legislation, which also means that these
packages are lead-free. The ICs have supply voltages of 8V, 5V and 3.3V.
UOC-TOP-64 is supported by a comprehensive Global TV Software Development kit to
enable easy programming and fast time-to-market (see also Section 20.4 “
Licenses”).

4.1.2Ripple Rejection
When both ramp signal and bias are provided by the same driver IC, you can gain natural rejec ti on
of any ripple caused by a vol tage drop in the ground (see Figure 5), if you manage to apply the
same fraction of ripple voltage to both booster inputs. For that purpose, arrange an intermediate
point in the bias resistor bridge, such that (R

4.2AC-Coupled Applications
In AC-coupled applications (See Figure 6), only one supply (VS) is needed. The vertical position of
the scanning cannot be adjusted with input bias (for that purpose, usually some current is injected
or sunk with a resistor in the low side of the yoke).
