TDA9105 Deflection Processor for Multi-Sync Monitors 12V 40mA IC DIP-42 (Wide)

Description

TDA9105 Deflection Processor for Multi-Sync Monitors 12V 40mA IC DIP-42 (Wide) The TDA9105 is a highly integrated deflection processor designed for multi-sync CRT monitor applications. It combines horizontal and vertical synchronization processing, dual phase-locked loops (PLLs), horizontal drive generation, vertical ramp generation, East-West correction, dynamic horizontal phase correction, and dynamic focus control within a single device. This integration significantly reduces external component count while providing accurate control of display geometry and scanning functions. The TDA9105 device supports a wide range of horizontal and vertical synchronization frequencies, making it suitable for multisync monitor systems. Built-in safety features include X-ray protection, supply voltage monitoring, lock/unlock detection, blanking control, and output shutdown functions. The TDA9105 also provides extensive geometry adjustments such as pincushion correction, trapezoid correction, side-pin balance, parallelogram correction, vertical size, vertical position, S-correction, and dynamic focus generation for high-quality CRT image reproduction.
