Working Principles

The SN65DSI86ZQER works by receiving DSI signals from a host processor and converting them into eDP signals compatible with high-resolution displays. It incorporates level shifters and pre-emphasis circuits to condition the signals for optimal transmission. The bridge also supports power-saving modes to reduce power consumption when the display is idle. Spread spectrum clocking is employed to minimize electromagnetic interference. The converted eDP signals are then transmitted to the display panel, enabling the rendering of high-quality images.

Detailed Application Field Plans

The SN65DSI86ZQER is widely used in various applications that require the conversion of DSI signals to eDP signals. Some common application fields include:

1. Mobile Devices: Smartphones, tablets, and portable gaming consoles often utilize high-resolution displays that require DSI to eDP conversion.
2. Automotive Infotainment Systems: In-car displays and infotainment systems benefit from the high-speed data transfer and low power consumption offered by the SN65DSI86ZQER.
3. Industrial Control Panels: The bridge enables the connection of DSI-based control panels to eDP-compatible display modules in industrial settings.
4. Medical Devices: Medical equipment such as ultrasound machines and patient monitors can leverage the SN65DSI86ZQER for driving high-resolution displays.
