Parade Technologies has launched PS8311 DisplayPort Repeater device thatit claims to enhance the output signal quality of a DisplayPort transmitter or ‘source,’ such as a GPU.
Using adaptive equalisation technology, the new PS8311 device removes signal distortion introduced by long PCB (printed circuit board) traces and by long or marginal connectors within the DisplayPort signal path between a GPU source and display sink.
Parade said that the new PS8311 device provides enhanced performance and integration for dual-mode or multi-mode DisplayPort Source devices. It responds to Link Training commands between the Source and Sink systems and, using the company’s ‘AUX Channel interceptor’ circuit, the device monitors the DisplayPort AUX Channel communication between the Source and Sink systems.
The company said that the PS8311 includes a new Automatic Equalisation Adjustment feature that adjusts the input gain and equalisation level based on the link training commands. This compensates for expected input level changes, and also allows the PS8311 to be placed closer to the original DisplayPort Source device, where amplitude and pre-emphasis levels will be higher.
The PS8311 comes with Automatic Power Management, which is expected to reduce overall power consumption. It detects the absence of a Sink device, such as a display and will power down until a Sink device is connected, the company said.
