DisplayPort 1.2a to DisplayPort (Dual Mode) Converter

Description

The STDP2690 is a high-speed DisplayPort-to-DisplayPort dual mode converter targeted for Mobile PC, TV and cable accessory applications. This device includes a VESA DP Standard Ver.1.2a compliant receiver and a DP1.2 dual mode transmitter. This device also functions as DP-to-DP re-timer.

The DisplayPort receiver and transmitter supports HBR2 speed, a data rate of 5.4 Gbps per lane with a total bandwidth of 21.6 Gbps link rate. The transmitter is capable of supporting HDMI or single link DVI output through a passive level translator (dongle). The HDMI transmitter supports link rate up to 2.97 Gbps that corresponds to a pixel rate of 297 MHz, adequate for handling video resolution up to FHD 120 Hz 3D formats or 4K2K 30Hz This device delivers deep color video up to 16-bits per color in RGB or YCbCr color format and 8-CH audio transport from the source to audio rendering device over the DP++ or through the SPDIF output.

The STDP2690 provides HDCP 1.x content protection both on the input and output port thus functions as HDCP repeater. It also supports the eDP authentication option ASSR (Alternative Scrambler Seed Reset) for embedded applications.
