TDA8841 datasheet

Description

The various versions of the TDA8841 series are I2C-bus controlled single chip TV processors which are intended to be applied in PAL, NTSC, PAL/NTSC and multi-standard television receivers. The N2 version is pin and application compatible with the N1 version, however,
a new feature has been added which makes the N2 more attractive. The IF PLL demodulator has been replaced by an alignment-free IF PLL demodulator with internal VCO (no tuned circuit required).

Features

1. Multi-standard vision IF circuit with an alignment-free PLL demodulator without external components

2. Alignment-free multi-standard FM sound demodulator (4.5 MHz to 6.5 MHz)

3. Audio switch

4. Flexible source selection with CVBS switch and Y(CVBS)/C input so that a comb filter can be applied

5. Integrated chrominance trap circuit

6. Integrated luminance delay line

7. Asymmetrical peaking in the luminance channel with a (defeatable) noise coring function

8. Black stretching of non-standard CVBS or luminance signals

9. Integrated chroma band-pass filter with switchable centre frequency

VCT49XYI TV Processor

Description

The VCT49xyI, VCT48xyI is an IC family of high-quality single-chip TV processors. Modular design and deep-submicron technology allow the economic integration of features in all classes of single-scan TV sets.

The VCT 49xyI, VCT 48xyI family is based on functional blocks contained and approved in existing
products like DRX 396xA, MSP 34x5G, VSP 94x7B, DDP 3315C, and SDA 55xx.

Each member of the family contains the entire IF, audio, video, display, and deflection processing for 4:3 and 16:9 50/60-Hz mono and stereo TV sets. The integrated microcontroller is supported by a powerful OSD generator with integrated Teletext & CC acquisition including on-chip page memory.
