LM1295
Description
The LM1295 is specifically designed for use in a continuous sync monitor. The injection-locked vertical oscillator operates from 50 Hz to 170 Hz, covering all known video monitors. A differential output current is provided in order to prevent ground interaction. The IC provides two outputs posed of the summation of DC controlled 1st and 2nd order output terms. The first output corrects for EW pincushion and trapezoid. The second corrects for parallelogram and bow. A DC controlled output is provided for vertical dynamic focus correction. The IC is packaged in a 24-pin narrow DIP package and operates on a single 12V power supply.
