Philips TDA4858 Economy Autosync Deflection Controller (EASDC) Datasheet
The TDA4858 is a high‑performance autosync deflection controller designed for video monitors. It provides full horizontal and vertical autosync, extensive geometry‑control functions, and a flexible switched‑mode power‑supply block. The device is fully DC‑controllable and includes X‑ray protection and a safe start‑up/shut‑down sequence for all power components.
The datasheet details the pin configuration, electrical specifications, functional blocks such as the frequency‑locked loop, PLL detectors, and video‑clamping generator. It also describes package dimensions (SDIP‑32) and soldering recommendations for reliable mounting.
