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 synchronization and deflection in color CRT displays and also accepts TTL input. It is a multifunctional IC aiming at high−quality picture reproduction.

Features:

● 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.

● 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 seperate input type only.

● Multifunctional and small−sized 6 Pin Dual−In−Line Package.
