Dual-mode DisplayPort™ version 1.2 Repeater

The PS8330 is a 1-to-1 DisplayPort version 1.2 repeater, or redriver, that supports dual-mode DisplayPort operation.

Specifically designed for the higher data rates of DisplayPort 1.2:

  • Link Rates of 5.4Gb/s (HBR2), 2.7Gb/s (HBR), and 1.62Gb/s (RBR)
  • AUX Channel rate of 720 Mb/s (Fast AUX) and 1 Mb/s (Standard AUX)

The PS8330 is designed to be used in a DisplayPort source system near the output receptacle, and it removes signal loss resulting from internal system distribution through use of an automatic equalizer. A clean, compliant DisplayPort output is regenerated by output drivers. Like the field-proven PS8121ED and PS8311 DisplayPort 1.1a repeaters, the PS8330 uses AUX channel interception, or snooping, that enables it to respond to cable drive requirements indicated by the sink device during link training. The device supports both I2C and pin enabled control options and supports automated source system compliance testing.
