Overview
TBA990J PAL "TV CHROMA DEMODULATOR FAIRCHILD LINEAR INTEGRATED CIRCUIT G E N E R A L D E S C R I P T I O N - T h e T B A 9 9 0 is an i n t e g r a t e d c o l o r d e m o d u l a t o r c i r c u i t for color television receivers incorporating two active synchronous demodulators for the R-V and B-Y chrominance signals, a matrix (producing the G-Y color difference signal), P A L phase switch and flip-flop.
It is suitable for dc c o u p l e d d r i v e t o t h e p i c t u r e tube.
W h e n associated w i t h t h e m a t r i x i n t e g r a t e d circuit (TBA530) it provides RGB output signals.
Special a t t e n t i o n has been given in the design to m i n i m i z i n g dc level d r i f t w i t h temperature and d i r e c t i n t e r f a c e w i t h T B A 5 3 0 , T B A 5 4 0 and T B A 5 6 0 .
It is c o n s t r u c t e d on a single s i l i c o n c h i p using the Fairchild Planar* process.
