April 21, 2020 Tiera Oliver

Diodes Incorporated announced the industry's first DisplayPort 2.0 (UHBR10) compliant 4-lane, 2:1 active switch with multiplexer and ReDriver, the PI3DPX8121. The device joins the company's portfolio of DisplayPort switching and signal conditioning solutions.

DisplayPort was developed to provide data transfer of high-resolution digital video with audio. Version 2.0 of the DisplayPort specification covers three data rates: 10Gbps (UHBR10), 13.5Gbps (UHBR13.5), and 20Gbps (UHBR20). According to the company, the PI3DPX8121 is currently the only product that supports the base speed of 10Gbps and includes the multiplexing function noted in the specification.

According to the company, DisplayPort 2.0 increases the available bandwidth compared with DisplayPort 1.4, which has a maximum data rate of 8.1Gbps per lane. The PI3DPX8121 ReDriver is compatible with both DisplayPort 1.4 and 2.0 (UHBR10). The device also offers protocol agnostic operation, supporting LTTPR (Link Training Transparent PHY Repeater) redrive data path type.

The device integrates CTLE equalizers at the inputs to reduce ISI jitter and compensate for channel loss. PI3DPX8121 also offers programmable flat gain and linearity adjustments.

The PI3DPX8121 is available now, priced at $1.65 each in 3000 piece quantities. New consumer products featuring DisplayPort 2.0 are expected by early 2021.
