S1D2512X01 DEFLECTION PROCESSOR FOR MULTISYNC MONITORS

DEFLECTION PROCESSOR

32-SDIP-400

The S1D2512X01 is a monolithic integrated circuit assembled in 32 pins
shrunk dual in line plastic package. This IC controls all the functions
related to the horizontal and vertical deflection in multi modes or multi­frequency computer display monitors.

The internal sync processor, combined with the very powerful geometry
correction block make the S1D2512X01 suitable for very high
performance monitors with very few external components. The horizontal
jitter level is very low. It is particularly well suited for high-end 17” and
19” monitors.

FUNCTIONS
