Overview
INTEGRATED CIRCUITS DATA SHEET TDA837x family I2C-bus controlled economy PAL/NTSC and NTSC TV-processors Preliminary specification File under Integrated Circuits, IC02 1997 Jul 01 Philips Semiconductors Preliminary specification I2C-bus controlled economy PAL/NTSC and NTSC TV-processors 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 • Flexible source selection with a CVBS input for the 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 functions • Low dissipation • Small amount of peripheral components compared with competition ICs.
Table 1 TV receiver versions SDIP56 PACKAGE TV RECEIVERS ECONOMY PAL only PAL/NTSC (SECAM) NTSC TDA8374B TDA8374 and TDA8374A TDA8373 MID/HIGH END − TDA8375 and TDA8375A TDA8377 and TDA8377A GENERAL DESCRIPTION TDA837x family 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 compatible so that with one application b...
