Philips Healthcare | Diagnostic Ultrasound System Hardware | Printed Circuit Board Components | Model 453561278213 | Unified AVIO Assembly Board | Rear I/O Backplane Interface Module

The Philips 453561278213 is a professional-grade, high-performance medical electronics assembly engineered as the core Unified AVIO (Audio Video Input Output) printed circuit board (PCB) backplane interface for premium Philips iE33 and iU22 intelligent diagnostic ultrasound systems. Functioning as the primary centralized routing bridge between the system's internal front-end data processing computers and the rear external peripheral panel, this multi-layer motherboard manages high-speed video signals, audio data streams, digital storage connectivity ports, and network communication channels. Manufactured to exact original equipment manufacturer (OEM) tolerances using medical-grade solid-state components, the Unified AVIO assembly features integrated surface-mount circuitry, specialized logic chipsets, and high-density terminal interface bus arrays designed to provide clean data pathway separation, reduce electromotive signal interference, suppress diagnostic image noise degradation, and replace older legacy module strings (such as the 453561278212 sequence) to maintain stable, long-term system uptime across busy cardiac and general imaging radiology environments.
