*The video encoder is the component signal processing for Y and C of 8 bit each as an internal processing. The dot
clock in the table above corresponds to the sampling clock at the time of 16bit processing of Y+C. To simplify post
filter, the video encoder processing performs ×2 oversampling. Therefore, the operation clock in video encoder part is
double of dot clock (27MHz, 24.54MHz, 29.5MHz, etc.).
