FEATURES Available in all ICs: - Vision IF amplifier with high sensitivity and good figures for differential phase and gain - PLL demodulator for the IF signal - Alignment-free sound demodulator w w w . D a t a source S h eselection e t 4 with U . ac CVBS o m input for the - Flexible TDA837x family GENERAL DESCRIPTION The various versions of the TDA837x series are I2C-bus controlled single-chip TV processors which are intended to be applied in PAL/NTSC (TDA8374 and TDA8375) and NTSC (TDA8373 and TDA8377) television receivers. All ICs are available in an SDIP56 package and some versions are also available in a QFP64 package. The ICs are pin patible so that with one application board NTSC and PAL/NTSC (or multistandard together with the SECAM decoder TDA8395) receivers can be built. Functionally this IC series is split in to 2 categories: - Versions intended to be used in economy TV receivers with all basic functions - Versions with additional functions such as E-W geometry control, horizontal and vertical zoom function and YUV interface which are intended for TV receivers with 110° picture tubes. The various type numbers are given in Table 1. The detailed differences between the various ICs are given in Table 2. internal signal and Y/C or CVBS input for the external signal - Audio switch - The output signal of the CVBS (Y/C) switch is externally available - Integrated chrominance trap and band-pass filters (auto-calibrated) - Luminance delay line integrated - A symmetrical peaking circuit in the luminance channel - Black stretching of non-standard CVBS or luminance signals - RGB control circuit with black current stabilization and white point adjustment - Linear RGB inputs and fast blanking - Horizontal synchronization with two control loops and alignment-free horizontal oscillator - Slow start and slow stop of the horizontal drive pulses - Vertical count-down circuit - Vertical driver optimized for DC-coupled vertical output stages - I2C-bus control of various...
