NXP Semiconductors TDA9177
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. It should preferably be used in front of an RGB video signal processor with YUV interface. The TDA9177 can be used as a cost effective alternative to (but also in combination with) Scan Velocity Modulation (SVM).| Part No. | TDA9177 |

ambient light control). QUICK REFERENCE DATA SYMBOL VCC Vi(Y) Vi(UV) VFS(ADC) Vref PARAMETER supply voltage luminance input voltage UV input voltage full scale ADC input voltage reference voltage AMS = LOW AMS = HIGH CONDITIONS MIN. 7.2 − − − − 3.90 TYP. 8.0 0.315 1.0 − 4.05 TDA9177 In combination with the TDA9170, it builds a high performance and intelligent picture improvement solution. The sharpness processor provides 1D luminance step improvement and detail enhancement by smart peaking, suitable for both 1fH and 2fH applications. An on-board 6-bit Analog-to-Digital Converter (ADC) can be used for interfacing two analog, low frequency voltage signals to the I2C-bus.
