Overview
The STDP4320BA is a high-speed DisplayPort dual mode splitter integrated circuit (IC) manufactured by Kinetic Technologies. This device is designed to split a DisplayPort 1.2 input signal into two identical outputs, making it ideal for various audio-video de-multiplexing and routing applications. The STDP4320BA is compliant with the DisplayPort 1.2a standard and supports advanced features such as Multi-Stream Transport (MST), High Bit Rate 2 (HBR2), and 3D formats. It also functions as an HDMI/DVI transmitter and receiver, allowing for compatibility with both DisplayPort and legacy video interfaces.
