OM8378PS/N3/2 Product Details

INTEGRATED CIRCUITS DEVICE DATASPECIFICATION SHEET OM8373; OM8378 TV signal processor- Closed Caption decoder with embedded µ-Controller Tentative Device Specification File under Integrated Circuits, Version: 1.0 2004 Jan 15 Previous version: Philips Semiconductors Tentative Device Specification TV signal processor- Closed Caption decoder with embedded µ-Controller GENERAL DESCRIPTION The OM8373 and OM8378 combine the functions of a video processor together with a µ-Controller and US Closed Caption decoder. The ICs are intended to be used in economy television receivers with 110° picture tubes. The ICs have supply voltages of 8 V and 3.3 V and they are mounted in a SDIP-64 envelope. The features are given in the following feature list. OM8373; OM8378 FEATURES TV-signal processor • Vision IF circuit suitable for negative modulation with alignment-free PLL demodulator • Internal (switchable) time-constant for the IF-AGC circuit • The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be switched to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such that the external band-pass filters can be omitted. • Source selection between the ‘internal’ CVBS and an external CVBS or Y/C signal • 1 external audio input. • Integrated chrominance trap circuit • Integrated luminance delay line with adjustable delay time • Picture improvement features with peaking (with switchable centre frequency, depeaking, variable positive/negative overshoot ratio and video dependent coring), dynamic skin tone control and blue- and black stretching. All features are available for CVBS, Y/C and YPBPR signals. • Tint control for all internal and external signals • Integrated chroma band-pass filter with switchable centre frequency • Only one reference (12 MHz) crystal required for the µ-Controller and the colour decoder • NTSC or PAL/NTSC colour decoder with automatic search system • Internal base-band delay line • Indication of the Signal-to-Noise ratio of the incoming CVBS signal • A linear RGB/YUV/YPBPR input with fast blanking for external RGB/YUV sources. The synchronisation circuit can be connected to the incoming Y signal. The OSD signals are internally supplied from the µ-Controller. • RGB control circuit with ‘Continuous Cathode Calibration’, white point and black level off-set adjustment so that the colour temperature of the dark and the light parts of the screen can be chosen independently. • 2 levels of contrast reduction of main picture possible during OSD/Text insertion (‘halftone’) • OSD/Text gain reduction control • Adjustable ‘wide blanking’ of the RGB outputs • Horizontal synchronization with two control loops and alignment-free horizontal oscillator • Vertical count-down circuit • Vertical driver optimized for DC-coupled vertical output stages • Horizontal and vertical geometry processing • Horizontal and v
