NXP Semiconductors TDA8755
The TDA8755 is a bipolar 8-bit video low-power analog-to-digital conversion (ADC) interface for YUV signals. The device converts the YUV analog input signal into 8-bit coded digital words in a 4 : 1 : 1 format at a sampling rate of 20 MHz. The U/V signals are converted in a multiplexed manner.| Part No. | TDA8755 |
