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.
VGA

(Fig. 1. Tuner section)

Small Signal Processing Section
Small signal processing section is the IF (intermediate frequency) signal across saw filter send in the pin12 and pin13 of IC201. The VIFIN signal through built-in PLL DEMOD, sound trap, video amplifier and synchronous detector processing, get the color video broadcast signal and 2nd sound IF signal. Video signal processing section is CVBS across video filter and delay line and horizontal & vertical synchronous separation circuit processing and get H-drive (pin56 of IC201)and V-drive signal (pin15/pin15 of IC201). IF sound signal across the sound-down-mixer and AM demodulator processing, send out the AVL/ SSIF OUT signal. ( Refer to Fig2 and Fig 3.)

(Fig 2. Small Signal Processing Section)

(Fig3. Block Diagram of IC201.)

Horizontal Scanning Section
The horizontal drive signal send out from pin 56 of IC201, Q401 is horizontal driving transistor, coupled by horizontal driving transformer T402 , to control the horizontal output transistor working in switch on and off situation, get good linearly and enough amplitude of saw-tooth wave current to drive horizontal deflection yoke scanning. L456 is horizontal width coil and L458 is horizontal linearly coil. D455 is damping diode, C453,C455,C457 are retrace capacitors. T401 is FBT. Pin2 of T401 is B+ voltage input, Pin 10 of T401 get 200 Volt video amplifying voltage supply for CRT board. Pin11 of T401 sends out heater voltage supply for CRT heater.

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.

Fig 4. Vertical Scanning Processing Section

CRT Scanning Section
Q507,D501,D502 and D503 makes up a light eliminate circuit network. When the TV is playing mode, +8V voltage across R533 charge for C512, Q507 is cut off. At the right of turn off the TV, Q507 is turn-on, the current across D501, D502 and D503 send to R.G. B to discharge the electronic quickly.

Audio Power Amplifying Section

Power Supply Section
AC supply 220V/110v through filtering network and rectifying circuit and get 300Vdc voltage. LF801/LF801A and CX802 makes up a differential mode rejection, LF802 and CY801,CY802 makes up a common mode rejection network. D801-D804 is rectifying network. 300Vdc voltage supply pin3 of T801, also through R804 send to pin8 of IC801 NCP1337. Pin5 of IC801 sends out the PWM signal to control Q801 working in switch on and off situation. IC803 is optocoupler.

UOC-TOP-64 N1 series
Versatile signal processor for CRT TV applications
Rev. 0.11 -- 25 January 2007 Product 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 2fH 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").

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 Multi-standard color decoder with automatic search system and various "forced mode" possibilities Internal base-band delay line Indication of the Signal-to-Noise ratio of the incoming CVBS signal Linear RGB/YPBPR input. Scan Velocity Modulation output. The SVM circuit is active for all the incoming CVBS, Y/C and RGB/YPBPR signals. The SVM output is combined with the black current input of the black current stabilisation circuit. By means of a small application adaptation both functions can be operational in parallel.

The supply voltage for the analogue audio part of the mono-90 version can be 5V or 8V. For a supply voltage of 5V the maximum signal amplitudes at in and outputs are 1Vrms. For a supply voltage of 8V the maximum output signal amplitude is 2 Vrms. The AV-110/90 and Mono-110 versions need a supply voltage of 8 V. The YPBPR input signal amplitudes are based on a color bar signal with 100% saturation.

The function of these pins is dependent on some I2C-bus control bits. More details are given in Table 7. The function of this pin is selected by means of the CMB2-0 bits The function of this pin is selected by means of the SVO1-0 bits The SSIF input is selected by means of the SSIFM bit The choice between two mono inputs or one stereo input is realized by means of the bits SAS3-0 The black current input, vertical guard input and SVM output (AV-110/90 and Mono-110 versions) have been combined on this pin. For a reliable operation of the protection system and the black current stabilization system or SVM system, the end of the vertical guard protection pulse during normal operation should not overlap the measuring pulses. Therefore this pulse must end before line 14.
