M35052-XXXSP/FP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
The M35052-XXXSP/FP is 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 separa-
tion) circuit, the synchronous correction circuit, the Decoder circuit,
and to the Encoder circuit, external circuits can be decrease and
character turbulence that occurs when superimposing can be reduced.
The processor can conform to the EDS broadcast service and is suit-
able for AV systems such as VTRs, LDs, and so on.
