DESCRIPTION

The M35054-XXXFP and M35055-XXXFP are TV screen display control IC which can be used to display information such as number of channels, the date and messages and program schedules on the TV screen.

In particular, owing to the built-in SYNC-SEP (synchronous separation) circuit, the synchronous correction circuit, external circuits can be decrease and character turbulence that occurs when superimposing can be reduced. The processor is suitable for AV systems such as VTRs, LDs, and so on.
