DisplayPort 2.0 active switch is an industry-first, says Diodes
Claimed to be the industry’s first DisplayPort 2.0 (UHBR10) -compliant four-lane, 2:1 active switch with multiplexer and ReDriver, the PI3DPX8121 has been added to Diode’s DisplayPort switching and signal conditioning portfolio. It is designed for PCs, monitors, set-top boxes and other audio visual equipment.
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: 10Gbits per second (UHBR10), 13.5Gbits per second (UHBR13.5) and 20Gbits per second (UHBR20). The PI3DPX8121 is believed to be the only product that supports the base speed of 10Gbits per second and includes the specification’s multiplexing function.
DisplayPort 2.0 increases the available bandwidth compared with DisplayPort 1.4, which has a maximum data rate of 8.1Gbits per second per lane. The higher bandwidth mitigates the need for data compression, explains Diodes, for faster systems overall.
New consumer products featuring DisplayPort 2.0 are expected by early 2021 and the PI3DPX8121 is poised to help manufacturers meet that 10Gbits per second (UHBR10) target.
The PI3DPX8121 ReDriver is compatible with both DisplayPort 1.4 and 2.0 (UHBR10). It also offers protocol agnostic operation, supporting (link training transparent PHY repeater (LTTPR) redrive data path type.
The device integrates continuous time linear equation (CTLE) equalisers at the inputs to reduce inter symbol interference (ISI) jitter and compensate for channel loss. PI3DPX8121 also offers programmable flat gain and linearity adjustments.
The PI3DPX8121 is available now from Diodes.
