1. Description

The STDP2650 is a high-speed DisplayPort-to-HDMI protocol converter or HDMI-to-HDMI re-timer IC for
applications such as audio-video cable accessories, docking stations, and TV front-end design. This device
includes a VESA DP Standard Ver.1.2a compliant dual-mode receiver and an HDMI 1.4 compliant transmitter.
The DisplayPort dual-mode input port comprises four main lanes, AUX CH, and HPD signal. The main lanes
can receive either a DP or TMDS signal format. The HDMI output port includes DDC, CEC, and HPD
support.
The STDP2650 uses Kinetic’s latest generation DisplayPort dual-mode 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. It can also
receive TMDS signal up to 2.97 Gbps per data pair. The HDMI transmitter is capable of supporting 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. 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 eDP authentication option ASSR (Alternative Scrambler Seed Reset) is supported for embedded
application.
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. This 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. In addition, it allows register level
configuration from an external host controller through I2C interface.
