... The PCA8515 supports three different TV scanning standards. To obtain the best quality character display, each TV standard requires a different OSD frequency. To cater for this requirement the PCA8515 provides a programmable OSD clock that generates frequencies in the range MHz. The two examples given below illustrate the OSD clock requirements for different TV scanning standards ...
