Block Diagram
The block diagram shows four HD input/output paths, video processing, audio interfaces, and EDID/HPD management inside MS9604.
Key Features
- Four independent HD inputs and outputs for multi-view processing and routing.
- Supports 4K @ 30 Hz and multiple color spaces/depths for mainstream HD formats.
- Automatic input detection and EQ simplify multi-source integration.
- Programmable EDID and HPD for multi-sink management.
- Integrated I²S/SPDIF digital audio path.
Typical Applications
- Multi-view HD video processing and matrices
- Multi-channel video composition and distribution in security systems
- Multi-signal scheduling in conferencing and production switchers
- OEM video solutions requiring four independent in/out channels
Design Notes
- MS9604 appears in both video switching and video processing categories; distinguish it from MS9601A (3x1 switch) during selection.
- Validate power, thermal design, and EDID strategy when all four channels operate simultaneously.
- HLQFP-216 is a large package; pay attention to PCB layout and signal integrity.
- Refer to the official datasheet for registers, processing capabilities, and firmware support.
