... Philips Semiconductors 2 I C-bus controlled PAL/NTSC/SECAM TV processors Which colour standard the IC’s can decode depends on the external X-tals. The X-tal to be connected to pin 34 must have a frequency of 3.5 MHz (NTSC-M, PAL-M or PAL-N) and pin 35 can handle X-tals with a frequency of 4.4 and 3.5 MHz. Because the X-tal frequency is used to ...

... Philips Semiconductors 2 I C-bus controlled PAL/NTSC/SECAM TV processors An important property of the 2-point stabilisation is that the off-set as well as the gain of the RGB path is adjusted by the feedback loop. Hence the maximum drive voltage for the cathode is fixed by the relation between the test pulses, the reference current and the relative gain setting of the 3 channels ...

... Philips Semiconductors 2 I C-bus controlled PAL/NTSC/SECAM TV processors 26. Several versions have a YUV interface. The luminance and colour difference out- and inputs can directly be connected. When additional picture improvement IC’s (like the TDA 9170) are applied the inputs of these IC’s must be ac coupled because of the black level clamp requirement. The output signal of the picture improvement IC can directly be coupled to the luminance and colour difference inputs as long as the dc level of these signals have a value between 1 and 7 Volts (for the luminance signal) or between 1 and 4 Volts (for the UV signals) ...

... Philips Semiconductors 2 I C-bus controlled PAL/NTSC/SECAM TV processors 33. During switch-on the horizontal output starts with the double frequency and with a duty cycle of 75% (VOUT = high). After about 50 ms the frequency is changed to the normal value. Because of the high frequency the peak currents in the horizontal output transistor are limited. Also during switch-off the frequency is switched to the double value and the RGB drive is set to maximum so that the EHT capacitor is discharged ...

... Philips Semiconductors 2 I C-bus controlled PAL/NTSC/SECAM TV processors 47. Because of the 2-point black current stabilisation circuit both the black level and the amplitude of the RGB output signals depend on the drive characteristic of the picture tube. The system checks whether the returning measuring currents meet the requirement and adapts the output level and gain of the circuit when necessary. Therefore the typical value of the black level and amplitude at the output are just given as an indication for the design of the RGB output stage ...
