DisplayPort 2.0 active switch with multiplexer and ReDriver introduced

Diodes Incorporated announced what is claimed to be the industry's first DisplayPort 2.0 (UHBR10) compliant four-lane, 2:1 active switch with multiplexer and ReDriver, the PI3DPX8121. The device enters the company’s portfolio of DisplayPort switching, and signal conditioning solutions developed to satisfy the design demands of PCs, monitors, set-top boxes, and other AV equipment.

DisplayPort 2.0 extends the available bandwidth compared with DisplayPort 1.4, which has a maximum data rate of 8.1Gbps per lane. A major benefit of higher bandwidth is that it decreases the requirement for data compression, leading to faster systems overall. New consumer products featuring DisplayPort 2.0 are expected by early 2021 and the device is poised to assist manufacturers to meet that 10Gbps (UHBR10) target.

The device is compatible with both DisplayPort 1.4 and 2.0 (UHBR10), making it future-resilient. The device also provides protocol-agnostic operation, supporting LTTPR redrive data path type.

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