TDA9177
FEATURES
- Can be used in 1f H and 2f H applications
- Luminance step improvement
- Line width control
- Smart peaking for detail enhancement
- Embedded feature reduction facility for smart noise control
- pensating chrominance delay
- YUV interface
- Two additional pins for access to 6-bit ADC and I2C-bus
- Versatile I2C-bus and pin control for user adjustments. GENERAL DESCRIPTION
The TDA9177 is an I2C-bus controlled sharpness improvement IC with additional inputs for 6-bit analog-to-digital conversion to facilitate additional parameter measurement (e.g. ambient light control). It should preferably be used in front of an RGB video signal processor with YUV interface.
