Diodes Company Launches Adjustable Multitasking/Demultitasking Linear ReDriver

     Diodes introduced two new multiplexed/demultiplexed linear ReDrivers that support the 20Gbps DisplayPort Ultra High Bit Rate (UHBR20) transmission mode. These two ReDriver devices are the first in the industry to meet the high-speed data transmission requirements of DisplayPort.

     The typical input to output delay of PI3DPX20021 and PI3DPX20012 is only 0.5ns. These two devices are not limited by the protocol, and have the transparent characteristics of link training. When the input is idle, the power saving mode can be automatically entered by the input signal detection function. The newly launched ReDriver by Diodes is packaged with 32 pin TQFN, and its size is 3mm x 6mm. It is suitable for compact system design and can operate in the industrial temperature range of - 40 ° C to 85 ° C.

     PI3DPX20021 is a 2-to-1, 4-channel multitasking device, while PI3DPX20012 is a 1-to-2, 4-channel multitasking device. ReDriver is applicable to the output of graphics processor (GPU). It can share high-order graphics from a single display signal source to one of the two outputs, or share two display inputs on a single display, thus meeting the growing market demand. This product is applicable to various product applications, such as mobile workstations, e-sports laptops, displays, computing peripherals, wireless display adapters, industrial computers, docking station hardware, and KVM switches.

     These two ReDrivers support 8 kinds of equalizer adjustment settings, plus 4 kinds of output smoothing gain and output amplitude adjustment settings, which can more effectively tune the signal integrity. It can compensate for channel loss and eliminate intersymbol interference (ISI) to expand the channel range.
