TB1245N
VIDEO, CHROMA AND SYNCHRONIZING SIGNALS PROCESSING IC FOR PAL / NTSC / SECAM SYSTEM COLOR TV
TB1245N that is a signal processing IC for the PAL / NTSC / SECAM color TV system integrates video, chroma and synchronizing signal processing circuits together in a 56pin shrink DIP plastic package. TB1245N incorporates a high performance picture quality compensation circuit in the video section, an automatic PAL / NTSC / SECAM discrimination circuit in the chroma section, and an automatic 50 / 60 Hz discrimination circuit in the synchronizing section. Besides a crystal oscillator that internally generates 4.43 MHz, 3.58 MHz and M / N-PAL clock signals for color demodulation, there is a horizontal PLL circuit built in the IC. The PAL / SECAM demodulation circuit which is an adjustment-free circuit incorporates a 1H DL circuit inside for operating the base band signal processing system. Also, TB1245N makes it possible to set or control various functions through the built-in I2C bus line.

Input non-modulated 200 Vp-p (R-Y) chroma signal to pin 42. Measure noise amplitude nR and nB (mVp-p) appearing in color difference signals of pin 35 and pin 36 respectively. Find S / N ratio by the following equation.
SNB - S = 20log (2 2 x VBS / nB x 10E - 3) SNR - S = 20log (2 2 x VRS / nR x 10E - 3)

In the condition that SUB (IF) D5 = 1, perform the same measurement as the above step 2. Measurement results are expressed as trfBW and trfRW . Input 200 mVp-p (R-Y ID) standard 75% color bar signal (SECAM system) to pin 42. Attenuate the input signal to pin 42. Measure R-Y ID signal level at pin 42 that turns on / off the killer as eSK and eSC. In the condition that SUB (IF) D3 = 1, perform the same measurement as the above step 2 and express the measurement results as eSFK and eSFC. In the condition that SUB (IF) D3 = 0, D2 = 1, perform the same measurement as the above step 2 and express the measurement results as eSWK and eSWC.
