Diodes Incorporated claims the industry’s first DisplayPort 2.0 (UHBR10)-compliant four-lane, 2:1 active switch with multiplexer and ReDriver. Designed for PCs, monitors, set-top boxes, and other AV equipment, the PI3DPX8121 is compatible with both DisplayPort 1.4 and 2.0 (UHBR10), making it future-resilient. The device also offers protocol-agnostic operation, supporting Link Training Transparent PHY Repeater (LTTPR).
DisplayPort was developed to provide data transfer of high-resolution digital video with audio. The DisplayPort 2.0 specification covers three data rates: 10 Gbits/s (UHBR10), 13.5 Gbits/s (UHBR13.5), and 20 Gbits/s (UHBR20). The PI3DPX8121 is currently the only product that supports the base speed of 10 Gbits/s and includes the multiplexing function noted in the specification, according to Diodes Inc. New consumer products featuring DisplayPort 2.0 are expected by early 2021.
DisplayPort 2.0 increases the available bandwidth compared with DisplayPort 1.4, which has a maximum data rate of 8.1 Gbits/s per lane. The higher bandwidth mitigates the need for data compression, leading to faster systems overall, said the company.
The PI3DPX8121 integrates CTLE equalizers at the inputs to reduce ISI jitter and compensate for channel loss. It also offers programmable flat gain and linearity adjustments.
The PI3DPX8121 is available now, priced at $1.65 each in quantities of 3,000.
