Description

The various versions of the TDA9381 series combine the functions of a TV signal processor together with a m-Controller and US Closed Caption decoder. Most versions have a Teletext decoder on board. The Teletext decoder has an internal RAM memory for 1or 10 page text. The ICs are intended to be used in economy television receivers with 90° and 110° picture tubes.

Features

1. TV-signal processor

(1) Multi-standard vision IF circuit with alignment-free PLL demodulator

(2) Internal (switchable) time-constant for the IF-AGC circuit

(3) A choice can be made between versions with mono intercarrier sound FM demodulator and versions with QSS IF amplifier.

(4) The mono intercarrier sound versions have 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.

(5) Source selection between ‘internal’ CVBS and external CVBS or Y/C signals

(6) Integrated chrominance trap circuit

Description

The OM8370 is the latest developed by Philips semiconductor.

It connects MCU with TV Processor is integrated in three integrated circuits and can demodulate PAL and NTsC systems. A microcontroller (MCU) with a TV processor is a type of embedded system that combines the functionality of a microcontroller with that of a TV (television) processor. This combination enables the MCU to interface with television signals, process video and audio data, and perform various tasks related to television applications.

Features

1. TV processing.

(1) Built-in IF circuit free demodulator.

(2) The intrinsic time constant is controlled by the IF AGC circuit.

(3) The single-channel sound carrier IF has a sound phase-locked loop demodulation circuit, and the selectable frequencies are: ⒋5, 5.5, 6,0, 6.5MIIz.

(4) Internal CVIBs and external CVIBs or Y/C signal can be selected.

(5) Has a complete chrominance channel circuit.

(6) The brightness delay linear circuit for adjusting time is integrated inside.

2. CPU processing.

(1) Adopt sOC51CPU standard core control.

(2) The period of the control time is 1us.

(3) Built-in 32K × 8 or 48K × 8 bytes of read-only memory.

(4) Built-in 3.5K × 8 bytes of auxiliary random access memory (sufficient to meet the display requirements of 1. K × 8 bytes)

(5) 14-bit PWM integrated tuning voltage.
