Note) The CXD2458AR processes the composite SYNC and separate SYNC inputs with the same pins.

Therefore, care should be given to the following points when using the CXD2458AR.

1) During composite SYNC input, the XVD input pin should be set to L or left open.

2) During separate SYNC (XHD, XVD) input, the XVD width specification is from 2H to 10H.
