DEFLECTION PROCESSOR FOR MULTISYNC MONITORS
S1D2511B01
DEFLECTION PROCESSOR
32-SDIP-400
The S1D2511B01 is a monolithc integrated circuit
assembled in 32 pins shrunk dual in line plastic pack-
age. This IC controls all the functions related to the hori-
zontal and vertical deflection in multimodes or multi-
frequency computer display monitors.
The internal sync processor, combined with the very
powerful geometry correction block make the S1D2511B
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 15”
and 17” monitors.
