1. Description

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. 1.2a compliant receiver and transmitter, implementing single link DisplayPort input

and output ports comprising four Main lanes, AUX CH, and HPD.

The STDP2690 uses Kinetic’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. 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, 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 eDP

authentication option ASSR (Alternative Scrambler Seed Reset) is supported for embedded application.

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.

This 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. In addition, it

allows register level configuration from an external host controller through I2C interface.
