TDA9143

TDA9143概述

I2C-bus controlled, alignment-free PAL/NTSC/SECAM decoder/sync processor

GENERAL DESCRIPTION

The is an I2C-bus controlled, alignment-free PAL/NTSC/SECAM decoder/sync processor with blanking

facilities for PALplus and EDTV-2 signals. The TDA9143 has been designed for use with baseband chrominance

delay lines, and has a combined subcarrier frequency/comb filter enable signal for communication with a PAL/NTSC comb filter.

FEATURES

• Multi-standard colour decoder and sync processor for PAL, NTSC and SECAM

• PALplus helper blanking and EDTV-2 blanking

• I2C-bus controlled

• I2C-bus addresses hardware selectable

• Pin compatible with TDA9141

• Alignment free

• Few external components

• Designed for use with baseband delay lines

• Integrated video filters

• Adjustable luminance delay

• Noise detector with I2C-bus read-out

• Norm/no_norm detector with I2C-bus read-out

• CVBS or Y/C input, with automatic detection possibility

• CVBS output, provided I2C-bus address 8A is used

• Vertical divider system

• Two-level sandcastle signal

• VA synchronization pulse 3-state

• HA synchronization pulse or clamping pulse CLP input/output

• Line-locked clock output 6.75 MHz or 6.875 MHz or stand-alone I2C-bus output port

• Stand-alone I2C-bus input/output port

• Colour matrix and fast YUV switch

• Comb filter enable input/output with subcarrier frequency

• Internal bypass mode of external delay line for NTSC applications

• Low power standby mode with 3-state YUV outputs

• Fast blanking detector with I2C-bus read-out

• Blanked or unblanked sync on Youtby I2C-bus bit BSY

• Internal MACROVISION gating for the horizontal PLL enabled by bus bit EMG.
