3 Description
The TDES4940 is a V3Link Enhanced Video to
DisplayPort (DP) / Embedded DisplayPort (eDP)
bridge device. In conjunction with a V3Link Enhanced
Video serializer, the chipset receives a high-speed
serialized interface over low-cost 50 Ω coax or
STP/STQ cables. The TDES4940 is a VESA DP
v1.4a/eDP v1.4b compatible device that supports
advanced features such as HBR3, and SuperFrame
formats. The device supports video resolutions of
4K 30-bit color and higher. The V3Link Enhanced
Video supports video and audio data transmission
and full duplex control, including I2C, and GPIO data
over the same link. Consolidation of video data and
control over V3Link Enhanced Video lanes reduces
the interconnect size and weight and simplifies
system design. EMI is minimized by the use of low
voltage differential signaling, data scrambling, and
randomization. In compatible V3Link mode, the device
supports up to 2K resolutions with 24-bit color depth
over a single/dual link as well as HDCP v1.4 support
when paired with an HDCP capable serializer.
