Integrated Circuit
Sync Deflection Circuit for Color TV
Description:
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 synchro-
nization and deflection in color CRT displays and also accepts TTL input. It is a multifunctional IC aim-
ing at high−quality picture reproduction.
Features:
D Non−adjusting at vertical sync 50Hz/60Hz due to vertical pull−in range of 20Hz.
D Horizontal and vertical oscillations are stable against variations in ambient temperature and
supply voltage due to small warm−up drift.
D Small variation in horizontal oscillation frequency.
D Good linearity and interlace because DC bias at vertical output stage is subjected to sampling
control within retrace time.
D Any vertical blanking pulse width can be set by peripheral parts.
D The AFC defeat function is eliminated during vertical trigger period to use the NTE7123 as
horizontal/vertical sync seperate input type only.
D Multifunctional and small−sized 6 Pin Dual−In−Line Package.
