The S1D2511B01 is a graphics chip from Sega that can control the horizontal and vertical deflection of multi-mode or multi-frequency computer display monitors. It features self-adaptive, dual PLL concept, a maximum frequency of 150kHz, X-ray protection input, and can be controlled via I2C for horizontal duty cycle, horizontal position, free running frequency, and burn-in mode frequency generator.
The 1D2511B01 is a monolithic integrated circuit in a 32‑pin SDIP package that controls horizontal and vertical deflection functions for multi‑mode computer display monitors. It includes a sync processor, geometry correction block, and a B+ regulator with step‑up/step‑down DC‑DC conversion.
The document lists pin functions, electrical characteristics, absolute maximum ratings, and reference data such as frequency ranges, supply voltages, and operating temperature limits. An application circuit and block diagram illustrate typical usage in monitor designs.
