Any resolution and refresh rates are supported from 25 MHz up to 180 MHz pixel
clock rate at 24 bpp, or up to 240 MHz pixel clock rate at 18 bpp
Bits per color (bpc) supported1
6, 8 bits supported
10, 12, 16 bits supported by truncation to 8 MSBs
All VGA colorimetry formats (RGB) supported
Power modes (when the application design is as per Figure 4)
Active-mode power consumption: ~200 mW at WUXGA, 1920 1200, 60 Hz
(18 bpc)
410 W at Low-power mode
Supports slave I2C-bus interface for host debugging and configuration
1. Except for color depth beyond 8 bits, display resolutions and refresh rates are only limited to those which a standard 2-lane
DisplayPort configuration is able to support over 2.7 Gbit/s per lane of DP Main Link.
