STDP2690 Advanced DisplayPort to DisplayPort (dual mode) converter

The STDP2690 is a high-speed DisplayPort to DisplayPort dual mode converter IC targeted for applications such as audio-video accessories, docking stations, Thunderbolt storage devices, etc. This device includes a VESA DP Standard Ver. 1.2 compliant receiver and transmitter, implementing single link DisplayPort input and output ports comprising four Main lanes, AUX CH, and HPD.

The STDP2690 uses ST's latest generation DisplayPort dual mode transmitter technology that supports both DisplayPort and TMDS signal formats (DP++). DisplayPort receiver and transmitter support HBR2 speed, a data rate of 5.4 Gbps per lane with a total bandwidth of 21.6 Gbps link rate. In addition, the transmitter is capable of supporting HDMI or single link DVI output through a passive level translator (dongle). When configured as HDMI output, this device supports link rate up to 2.97 Gbps that corresponds to a pixel rate of 297 MHz, quite adequate for handling video timings up to FHD 120 Hz 3D formats. This device delivers deep color video up to 16-bits per color at 1080p 60 Hz and lower video resolutions. The STDP2690 allows audio transport from the source to desired audio rendering devices over the DP++ output or through the SPDIF port. The audio signal from the source can be routed simultaneously to DP++ and SPDIF output ports. For example, the STDP2690 allows routing of any two audio channels on the SPDIF port, while transporting up to eight channels on the DP++ port.

The STDP2690 supports RGB and YCbCr colorimetric formats with color depth of 16, 12, 10, and 8 bits. This device features HDCP 1.3 content protection scheme with an embedded key option for secure transmission of digital audio-video content. It also operates as an HDCP repeater for the downstream sink.

The AUX-to-I²C translator in the STDP2690 allows the upstream DisplayPort source to access EDID and transfer MCCS commands to a downstream sink over the HDMI interface when used with a level translator. The device has an on-chip microcontroller with SPI and I²C host interface for system configuration purposes. STDP2690 can be configured with an external SPI Flash for custom applications or simply configured from an external host controller through I²C interface
