The NTE7123 is an integrated circuit that has a wide vertical pull−in range of 20Hz and contains a generator of horizontal, vertical blanking as well as the main functions required to provide synchronization and deflection in color CRT displays. It also accepts TTL input. It is a multifunctional IC aiming at high−quality picture reproduction. Features include non−adjusting at vertical sync 50Hz/60Hz due to vertical pull−in range of 20Hz, horizontal and vertical oscillations are stable against variations in ambient temperature and supply voltage due to small warm−up drift, small variation in horizontal oscillation frequency and good linearity and interlace because DC bias at vertical output stage is subjected to sampling control within retrace time. Any vertical-blanking pulse width can be set by peripheral parts. The AFC defeat function is eliminated during vertical trigger period to use the NTE7123 as
horizontal/vertical sync separate input type only.
