Description
The STiDP880 is an internal DisplayPort to high-speed Dual LVDS/Quad LVDS converter IC
targeted for the interconnection between a TV controller SOC and panel TCON. STiDP880
is a proposed VESA iDP compliant device, implementing a single link internal DisplayPort
input comprising four Main Link lanes and HPD, which operates without a sideband channel.
This device supports the proposed standard iDP link rate of 3.24 Gbps per lane with a total
link bandwidth of 12.96 Gbps, allowing interface connectivity for a wide range of panels up
to FHD 120 Hz and 10 bits per color. The advanced equalizer built in this device offers
robust performance over FFC and UTP type cables.
The STiDP880 supports RGB video color formats with color depth of 10 and 8 bits. This
device offers LVDS output interface configurable to map a wide range of pixel data mapping,
such as JEIDA, non-JEIDA, and VESA types. The Quad LVDS interface supports video
signals up to 400 MHz pixel rate with flexible channel and lane swapping options. In Dual
LVDS configuration, STiDP880 can support up to 300 MHz pixel rate.
The STiDP880 is designed to operate in standalone mode (without any programming from
an external microcontroller) with default configuration of four lanes DP input and QLVDS
output with non-JEIDA mapping. However, the device is configurable from an external
microcontroller through I2C host interface for custom configuration.
