INTEGRATED CIRCUITS DATA SHEET TDA9177 YUV transient improvement processor Product specification Supersedes data of 1996 Jun 28 File under Integrated Circuits, IC02 1997 Dec 01 Philips Semiconductors Product specification YUV transient improvement processor FEATURES Can be used in 1fH and 2fH applications Luminance step improvement Line width control Smart peaking for detail enhancement Embedded feature reduction facility for smart noise control Compensating 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.
