TV signal processor-Teletext decoder with embedded µ-Controller

GENERAL DESCRIPTION

The various versions of theTDA935X/6X/8X PS/N2 series combine the functions of a TV signal processor together with a µ-Controller and US Closed Caption decoder. Most versions have a Teletext decoder on board. The Teletext decoderhasaninternal RAMmemory for1or 10page text. The ICs are intended to be used in economy television receivers with 90° and 110° picture tubes.

The ICs have supply voltages of 8 V and 3.3 V and they are mounted in S-DIP envelope with 64 pins.

The features are given in the following feature list. The differences between the various ICs are given in the table on page 4.

TDA935X/6X/8X PS/N2 series

FEATURES TV-signal processor

• Multi-standard vision IF circuit with alignment-free PLL demodulator

• Internal (switchable) time-constant forthe IF-AGC circuit

• A choice can be made between versions with mono

intercarrier sound FM demodulator and versions with QSS IF amplifier.

• The mono intercarrier sound versions have 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.

• Source selection between ‘internal’ CVBS and external CVBS or Y/C signals

• Integrated chrominance trap circuit

• Integrated luminance delay line with adjustable delay

time

• Picture improvement features with peaking (with variable centre frequency and positive/negative overshoot ratio) and black stretching

• Integrated chroma band-pass filter with switchable centre frequency

• Only one reference (12 MHz) crystal required for the µ-Controller, Teletext- and the colour decoder

• PAL/NTSC or multi-standard colour decoder with

automatic search system

• Internal base-band delay line

• RGB control circuit with ‘Continuous Cathode

Calibration’, white point and black level offset adjustment so that the colour temperature of the dark and the light parts of the screen can be chosen independently.

• Linear RGB or YUV input with fast blanking for external RGB/YUV sources. The Text/OSD signals are internally supplied from the µ-Controller/Teletext decoder

• Contrast reduction possibility during mixed-mode of OSD and Text signals

• Horizontal synchronization with two control loops and alignment-free horizontal oscillator

• Vertical count-down circuit

• Vertical driver optimized for DC-coupled vertical output

stages

• Horizontal and vertical geometry processing

• Horizontal and vertical zoom function for 16 : 9

applications

• Horizontal parallelogram and bow correction for large screen picture tubes

• Low-power start-up of the horizontal drive circuit

Note

1. The function of pin 20, 28, 29, 31, 32, 35 and 44 is dependent on the IC version (mono intercarrier FM demodulator / QSS IF amplifier and East-West output or not) and on some software control bits. The valid combinations are given in table 1.

2. The vertical guard function can be controlled via pin 49 or pin 50. The selction is made by means of the IVG bit in subaddress 2BH.

STA START ﬂag. When this bit is set in slave mode, the hardware checks the I2C bus and generates a START condition if the bus is free or after the bus

becomes free. If the device operates in master mode it will generate a repeated START condition.

STO STOP ﬂag. If this bit is set in a master mode a STOP condition is generated. A STOP condition detected on the I2C bus clears this bit. This bit may also

be set in slave mode in order to recover from an error condition. In this case no STOP condition is generated to the I2C bus, but the hardware releases the SDA and SCL lines and switches to the not selected receiver mode. The STOP ﬂag is cleared by the hardware.

SI Serial Interrupt ﬂag. This ﬂag is set and an interrupt request is generated, after any of the following events occur:

-A START condition is generated in master mode.

-The own slave address has been received during AA=1.

-The general call address has been received while S1ADR.GC and AA=1.

-A data byte has been received or transmitted in master mode (even if arbitration is lost).

-A data byte has been received or transmitted as selected slave. A STOP or START condition is received as selected slave receiver or transmitter While the SI ﬂag is set, SCL remains LOW and the serial transfer is suspened.SI must be reset by software.

AA Assert Acknowledge ﬂag. When this bit is set, an acknowledge is returned after any one of the following conditions

-Own slave address is received.

-General call address is received(S1ADR.GC=1).

-A data byte is received, while the device is programmed to be a master receiver.

-A data byte is received, while the device is selected slave receiver. When the bit is reset, no acknowledge is returned. Consequently, no interrupt is requested when the own address or general call address is received.

Power-on Reset

Power on reset is generated internally to the TDA935X/6x/8xdevice, henceno external resetcircuitry is required. The TV processor die shall generate the master reset in the system, which in turn will reset the microcontroller die

A external reset pin is still present and is logically ORed with the internal Power on reset. This pin will only be used fortest modes andOTP/ISP programming.The active high reset pin incorporates an internal pull-down, thus it can be left unconnected in application.

Power Saving modes of Operation

There are three Power Saving modes, Idle, Stand-by and Power Down, incorporated into the Painter1_Plus die. When utilizing either mode, the 3.3v power to the device (Vddp, Vddc & Vdda) should be maintained, since Power Saving is achieved by clock gating on a section by section basis.

STAND-BY MODE During Stand-by mode, the Acquisition and Display sections of the device are disabled. The following functions remain active:-

• 80c51 CPU Core

• Memory Interface

• I2C

• Timer/Counters

• WatchDog Timer

• SAD and PWMs

To enter Stand-by mode, the STAND-BY bit in the ROMBANK register must be set. Once in Stand-By, the XTAL oscillator continues to run, but the internal clock to Acquisitionand Display aregated out.However, the clocks to the 80c51 CPU Core, Memory Interface, I2C, Timer/Counters, WatchDog Timer and Pulse Width Modulators are maintained. Since the output values on RGB and VDS are maintained the display output must be disabled before entering this mode. This mode may be used in conjunction with both Idle and Power-Downmodes. Hence, prior to enteringeither Idle or Power-Down,the STAND-BY bit may beset, thus allowing wake-up of the 80c51 CPU core without fully waking the entire device (This enables detection of a Remote Control source in a power saving mode).

IDLE MODE During Idle mode, Acquisition, Display and the CPU sections of the device are disabled. The following functions remain active:-

• Memory Interface

• I2C

• Timer/Counters

• WatchDog Timer

• SAD & PWMs

To enter Idle mode the IDL bit in the PCON register must be set. The WatchDog timer must be disabled prior to enteringIdle to preventthe devicebeing reset. Oncein Idle mode,the XTALoscillator continuesto run,but the internal clock to the CPU, Acquisition and Display are gated out. However, the clocks to the Memory Interface, I2C, Timer/Counters, WatchDog Timer and Pulse Width Modulators are maintained. The CPU state is frozen along with the status of all SFRs, internal RAM contents are maintained, as are the device output pin values. Since the output values on RGB and VDS are maintained the Display output must be disabled before entering this mode. There are three methods available to recover from Idle:-

• Assertionof an enabled interrupt will cause theIDL bitto be cleared by hardware, thus terminating Idle mode. The interrupt is serviced, and following the instruction RETI, the next instruction to be executed will be the one after the instruction that put the device into Idle mode.

• A second method of exiting Idle is via an Interrupt generated by the SAD DC Compare circuit. When Painter is configured in this mode, detection of an analogue threshold at the input to the SAD may be used to trigger wake-up of the device i.e. TV Front Panel Key-press. As above, the interrupt is serviced, and following the instruction RETI, the next instruction to be

executedwill bethe onefollowing theinstruction that put the device into Idle.

• The third method of terminating Idle mode is with an external hardware reset. Since the oscillator is running, the hardware reset need only be active for two machine cycles (24 clocks at 12MHz) to complete the reset operation. Reset defines all SFRs and Display memory to a pre-defined state, but maintains all other RAM values. Code execution commences with the Program Counter set to ’0000’.

POWER DOWN MODE In Power Down mode the XTAL oscillator still runs, and differential clock transmitter is active. The contents of all SFRs and Data memory are maintained, however, the contentsof theAuxiliary/Display memoryare lost. The port pinsmaintain thevalues defined by their associatedSFRs. Since the output values on RGB and VDS are maintained the Display output must be made inactive before entering Power Down mode. The power down mode is activated by setting the PD bit in the PCON register. It is advised to disable the WatchDog timer prior to entering Power down. Recovery from Power-Down takes several milli-seconds as the oscillator must be given time to stabilise. There are three methods of exiting power down:-

• An External interrupt provides the first mechanism for waking from Power-Down. Since the clock is stopped, externalinterrupts needsto beset levelsensitive prior to entering Power-Down. The interrupt is serviced, and following the instruction RETI, the next instruction to be executed will be the one after the instruction that put the device into Power-Down mode.

• A second method of exiting Power-Down is via an Interrupt generated by the SAD DC Compare circuit. When Painter is configured in this mode, detection of a certain analogue threshold at the input to the SAD may be used to trigger wake-up of the device i.e. TV Front Panel Key-press. As above, the interrupt is serviced, andfollowing theinstruction RETI, the next instructionto be executed will be the one following the instruction that put the device into Power-Down.

• The third method of terminating the Power-Down mode is with an external hardware reset. Reset defines all SFRs and Display memory, but maintains all other RAM values. Code execution commences with the Program Counter set to ’0000’.
