PROTECTION AND LOCATION OF YOUR SET

15.1. If an outside antenna is connected to the television set, be sure the antenna system is grounded so as to provide some

protection against voltage surges and built up static charges, Section 810 of the National Electrical Code, NFPA No. 70-1975, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrode, and requirements for the grounding electrode.

15.2. Note to CATV system installer : (Only for the television set with CATV reception)

This reminder is provided to call the CATV system attention to Article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.

16. An outside antenna system should not be located in the vicinity of overhead power lines or other electric lights or power

circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

17. For added protection for this television set during a lightning storm, or when it is left unattended and unused for long

periods of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage due to lightning and power-line surges.

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.

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

and LCD TV receivers.

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

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”).

2. Features

2.1 Analog Video Processing

2.1.1 Overview of available features (AV-110/90 and Mono-110 concept)

 Multi-standard vision IF circuit with alignment-free PLL demodulator  Internal (switchable) time-constant for the IF-AGC circuit  Switchable group delay correction and sound trap (with switchable centre frequency)

for the demodulated CVBS signal

 Separate Second Sound IF output or FM demodulator output without de-emphasis

available, which can be used as input for an external BTSC decoder or as input for external sound band-pass filter for second language processing.

 Separate SSIF input available as input for the FM-PLL demodulator to demodulate

FM-radio with an IF frequency of 10.7 MHz, or as input from an external sound band-pass filter for second language processing.

 AM demodulator without extra reference circuit  The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be

switched to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such that the external band-pass filters can be omitted.

 The FM-PLL demodulator can be set to centre frequencies of 4.72/5.74 MHz so that a

second sound channel can be demodulated. In such an application it is necessary that an external bandpass filter is inserted.

 Audio switch circuit with 2 stereo inputs (1 stereo input can also be switched into two

mono sound inputs) and a stereo output which can be used for the drive of for audio power amplifiers (with volume and tone-control) or as SCART/CINCH output. The second stereo input is only available via the combined C2/C3/C4/AUDIOIN5R pin for the right channel and via the combined CVBS4/Y4/AUDIOIN5L pin for the left channel.

 Video switch with 3 external CVBS inputs. All CVBS inputs can be used as Y-input for

Y/C signals. However, only 1 Y/C source can be selected because the circuit has 1 chroma input. CVBS3/Y3 input available in combination with the G/Y-3 input pin.

 1 CVBS output, this output can be used as monitor video output or as front-end video

output or as independent selectable video output.

 Automatic Y/C signal detector.  Integrated luminance delay line with adjustable delay time  Only one reference (24.576 MHz) crystal required for the m-Controller, Teletext- and

the color decoder

STV8172A Application Hints

4 Application Hints

The yoke can be coupled either in AC or DC.

4.1 DC-coupled Application

When DC coupled (see Figure 4), the display vertical position can be adjusted with input bias. On the other hand, 2 supply sources (V

and -VEE) are required.

A Stand-by state will be reached by switching OFF the positive supply alone. In this state, where both inputs are the same volt age as pin 2 or higher, the output will sink negligib le current from the deviation coil.

4.1.1 Application Hints

For calculatio ns, treat the IC as an op-amp, where the feedback loop maintains V1 = V7.

4.1.1.1 Centering

Display will be centered (n ull mean current in yoke) when voltage on pin 7 is (R

is negligible):

4.1.1.2 Peak Current

Example: for V

=2V, VM = 5 V and IP =1A

Choose R

in the1 W range, for instance R1=1 W

From equation of peak current:

Then choose R

or R3. For instance, if R2 = 10 kW, then R3 = 15 kW

Finally, the bias voltage on pin 7 should be:

4.1.2 Ripple Rejection

When both ramp signal and bias are provided by the same driver IC, you can gain natural rejection of any ripple caused by a voltage 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

/ R7) = (R3 / R2), and connect the bias filtering

capacitor between the intermediate point and the local driver ground. Of course, R

should be

connected to the booster reference point, which is the ground side of R

4.2 AC-Coupled Applications

In AC-coupled appli cations (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 curr ent is injected or sunk with a resistor in the low side of the yoke).

4.2.1 Application Hints

Gain is defined as in the previous case:

Choose R

then either R2 or R3. For good output centering, V7 must fulfill the following equation:

CS performs an integration o f the par abolic si gnal on CL, therefore the amount of S correction is set by the combination of C

and Cs.

4.3 Application with Differential-output Drivers

Certain driver ICs provide the ramp signal in differential form, as two current sources i+ and i- with opposite variations.

Let us set some definitions:

● i

is the common-mode current:

● at peak of signal, i

+=icm

+ip and i-=icm -ip, therefore the peak differential signal is ip-(-

)=2ip, and the peak-peak differential signal, 4ip.

The application is described in Figure 7 with DC yoke coupling. The calculations sti ll rely on the fact that V

remains equal to V7.
