Description STDP2600

1 Description

The STDP2600 is a high-speed HDMI to DisplayPort converter IC targeted for applications
such as audio-video accessories, docking stations, notebook motherboard designs, etc.
This device includes an HDMI 1.4 compliant receiver and a VESA DP Standard Ver. 1.2
compliant dual mode transmitter, implementing a single link DisplayPort output port
comprising four Main lanes, AUX CH, and HPD.

The STDP2600 uses ST's latest generation DisplayPort dual mode transmitter technology
that supports both DisplayPort and TMDS signal formats (DP++). DisplayPort 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 also capable of supporting HDMI or single link DVI output
through a passive level translator (dongle). The HDMI receiver unit 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. STDP2600 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, STDP2600 allows routing of any two audio channels on
the SPDIF port, while transporting up to eight channels on the DP++ port.

The STDP2600 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 I2C-to-AUX translator in STDP2600 allows the upstream HDMI source to access EDID
and transfer MCCS commands to a downstream DisplayPort sink device over the
DisplayPort interface. This device has an on-chip microcontroller with SPI and I2C host
interface for system configuration purposes. STDP2600 can be configured with an external
SPI Flash for custom applications or simply configured from an external host controller
through I2C interface.
