Description STDP2650
1 Description
The STDP2650 is a high-speed DisplayPort to HDMI converter IC for applications such as
audio-video accessories for docking stations, TV front-end design, etc. This device includes
a VESA DP Standard Ver.1.2 compliant receiver and an HDMI 1.4 compliant transmitter.
The DisplayPort input port comprises four Main lanes, AUX CH, and HPD signal. The HDMI
output port includes DDC, CEC, and HPD support.
The STDP2650 uses ST's latest generation DisplayPort receiver technology that supports
HBR2 speed, a data rate of 5.4 Gbps per lane with a total bandwidth of 21.6 Gbps link rate.
The HDMI transmitter is capable of supporting link rate up to 2.97 Gbps that corresponds to
a pixel rate of 297 MHz, quite adequate for handling video resolution 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 STDP2650 allows audio transport from the source to desired
audio rendering devices over the HDMI output or through the SPDIF port. The audio signal
from the source can be routed simultaneously to HDMI and SPDIF output ports. For
example, the STDP2650 allows routing of any two audio channels on the SPDIF port, while
transporting up to eight channels on the HDMI port.
The STDP2650 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 STDP2650 allows the upstream DisplayPort source to
access EDID and transfer MCCS commands to a downstream sink over the HDMI interface.
The device has an on-chip microcontroller with SPI and I2C host interface for system
configuration purposes. The STDP2650 can be configured with an external SPI Flash for
custom applications or simply configured from an external host controller through I2C
interface.
