Versatile signal processor for low- and mid-range TV applications
GENERAL DESCRIPTION The UOCIII series combines the functions of a Video Signal Processor (VSP) together with a FLASH embedded TEXT/Control/Graphics µ-Controller (TCG µ-Controller) and US Closed Caption decoder. In addition the following functions can be added: · Adaptive digital (4H/2H) PAL/NTSC combfilter · Teletext decoder with 10 page text memory · Multi-standard stereo decoder · BTSC stereo decoder · Digital sound processing circuit · Digital video processing circuit The UOCIII series consists of the following 3 basic concepts: · Stereo versions. These versions contain the TV processor with a stereo audio selector, the TCG µ-Controller, the multi-standard stereo or BTSC decoder, the digital sound processing circuit and the digital video processing circuit. Options are the adaptive digital PAL/NTSC comb filter and a teletext decoder with 10 page text memory. · AV stereo versions. These versions contain the TV processor with stereo audio selector and the TCG µ-Controller. Options are the digital sound processing circuit, the digital video processing circuit, the adaptive digital PAL/NTSC comb filter and a teletext decoder with a 10 page text memory. · Mono sound versions. These versions contain the TV processor with a selector for mono audio signals and the TCG µ-Controller. Options are the adaptive digital PAL/NTSC combfilter and a teletext decoder with 10 page text memory. The most important features of the complete IC series are given in the following feature lists. The exact feature content of the various ICs is given in Table 1 on page 7. The ICs are mounted in a QFP-128 envelope(1) and can be used in economy television receivers with 90° and 110° picture tubes. They have supply voltages of 5V, 3.3V. Also an 1.8V supply is needed, but this can be simply derived by adding an emitter follower at a reference voltage from the device. UOCIII is supported by a comprehensive Global TV Software Development kit to enable easy programming and fast time-to-market (see also Chapter "LICENSE INFORMATION" on page 6.
(1) Both standard and "face down" versions of the QFP128 0.8mm pitch package are available.
UOCIII series
FEATURES Analogue Video Processing (all versions) · Multi-standard vision IF circuit with alignment-free PLL demodulator · Internal (switchable) time-constant for the IF-AGC circuit · Switchable group delay correction and sound trap (with switchable centre frequency) for the demodulated CVBS signal · DVB/VSB IF circuit for preprocessing of digital TV signals. · Video switch with 3 external CVBS inputs and a CVBS output. All CVBS inputs can be used as Y-input |
