Chrontel’s CH7530A is a low-cost, low-power semiconductor device that translates the DisplayPort dual

mode signal to TMDS signal. This innovative device,

which integrates programmable equalizer, high speed

TMDS level shifter and IIC to AUX translator, is specially

designed to target the DP++ adaptor device, docking

station and PC market segments.

The CH7530A is compliant with the DisplayPort dual

mode standard specification version 1.1. With

sophisticated equalizer and high-speed TMDS level shifter

integrated, the device’s TMDS signal output supports

video resolution up to 4Kx2K@30Hz or

1920x1080@120Hz for 3D applications.

The CH7530A also integrates the identifier, IIC over

AUX translator and the related DDC control registers,

which enables the programmable TMDS output and

supports both DDC and AUX signaling on the upstream

DisplayPort connector. With step-up regulator integrated,

CH7530A supports 5V power supply output.
