Video, Chroma and Deflection Circuit for

Color Television Sets

Overview

The LA7625 and LA7626 are based on the LA7620 and

LA7621 with the video circuit DC restoration factor changed

to 100%. The LA7625 and LA7626 are small, multifunction

ICs in which video, chroma and deflection circuits for NTSC

color TV system are packaged in a shrink-type DIP30S (the

same type as the earlier DIP22). In addition to being small,

these ICs greatly reduce the number of components required

and reduce the number of adjustments that must be made. By

combining the LA7625 or LA7626 with the LA7555 or

LA7577 VIF/SIF IC, or LA7832, LA7833, LA7837, or

LA7838 vertical output IC, it is possible to process all

functions of the color television signal system. Note that the

LA7625 has a peak clipping circuit built into the video circuit,

and is suited primarily for compact sets, while the LA7626

does not have a peak clipping circuit and is suited for larger

sets.
