TB1245N TENTATIVE TOSHIBA Bi-CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC 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. 1 Weight: 5.55 g (Typ.) 2001-07-26 TB1245N FEATURES = Video section · Built-in trap filter · Black expansion circuit · Variable DC regeneration rate · Y delay line · Sharpness control by aperture control · γ correction = Chroma section · Built-in 1 H Delay circuit · PAL base band demodulation · One crystal color demodulation circuit · Automatic system discrimination · Built-in band-pass filter · Color limiter circuit = Synchronizing deflecting section · Built-in horizontal VCO resonator · Adjustment-free horizontal / vertical oscillation By count-down circuit · Double AFC circuit · Vertical frequency automatic discrimination circuit · Horizontal / vertical holding adjustment · Vertical ramp output · Vertical amplitude adjustment · Vertical linearity / S-shaped curve adjustment · E / W output = Text section · Linear RGB input · OSD RGB input · Cut / off-drive adjustment · RGB primary signal output 2 2001-07-26 TB1245N BLOCK DIAGRAM 3 2001-07-26 TB1245N PIN No. 1 PIN NAME SCP OUTPUT FUNCTION INTERFACE CIRCUIT INPUT / OUTPUT SIGNAL Output terminal of Sand Castle Pulse.
