MULTI-COLOR VIDEO-CHROMA-DEFLECTION The TAS659AN is an NTSC/PAL/SECAM video- chroma-deflection sub-system with the teletext interface circuit. The TAS8659AN includes all of the functions required to realize a multi-color CTV in conjunction with a PIF/SIF IC, in a 64 leads shrink type dual-in-line plastic package. PEATURES - Realized a full automatic multi-color processing in conjunction with the TABGISN system switch, with minimal external components. Forced system selection.Forced system selection.
+ Automatic system change by a sub-carrier detection. . The mode change output can be used for switching the external components or circuits.
RCB interface with high switching speed, a half tone control and an independent contrast control.
