Product lineup
PS8331
Integrated DisplayPort™ 2:1 multiplexer compatible with DisplayPort™ 1.2 and dual-mode DisplayPort™ signaling. DisplayPort™ link rates up to 5.4Gbps and Fast AUX are supported. When used for native DisplayPort™ signaling, the PS8331 acts as a redriver by link training with a downstream DisplayPort™ sink.
When used as a dual-mode upstream source, the PS8331 supports the use of AC-coupled TMDS signals with up to 300MHz TMDS clock rates, and support for DVI or HDMI™ sink devices through the use of downstream level shifter devices or external dual-mode cable adapters. make it possible.

PS8461
Integrated DisplayPort™ 2:1 multiplexer compatible with DisplayPort™ 1.4 and dual-mode DisplayPort™ signaling. An internal retimer circuit is used for jitter cleaning of both native DisplayPort™ signals and TMDS signals enabled by dual-mode operation. Supports DisplayPort™ link rates up to 8.1Gbps, supports TMDS data rates up to 6Gbps, and enables support for HDMI™ 2.0b operation up to 40K@60Hz.
When used for native DisplayPort™ signaling, the PS8461's main link output swing and pre-emphasis level respond to link training between the DisplayPort™ video source and downstream sink by using transparent repeater operation. When used as a dual-mode upstream source, the PS8461 supports dual-mode AC-coupled TMDS signals. This allows support for DVI or HDMI™ sink devices through the use of downstream level shifting devices such as dual-mode DP to HDMI™ adapters.

PS8461E
Integrated DisplayPort™ 2:1 multiplexer compatible with DisplayPort™ 1.4a and dual-mode DisplayPort™ signaling. An internal retimer circuit is used for jitter cleaning of both native DisplayPort™ signals and TMDS signals enabled by dual-mode operation. Supports DisplayPort™ link rates up to 8.1Gbps, supports TMDS data rates up to 6Gbps, and enables support for HDMI™ 2.0b operation up to 40K@60Hz.
When used for native DisplayPort™ signaling, the PS8461E main link output swing and pre-emphasis level respond to link training between the DisplayPort™ video source and downstream sink by using transparent repeater operation. For Link Training Tunable PHY Repeater (LTTPR) operation, the PS8461E monitors the DisplayPort™ AUX channel and snoops LTTPR DPCD register transactions.
When used with dual-mode upstream sources, PS8461E supports dual-mode AC-coupled TMDS signaling. This allows support for DVI or HDMI™ sink devices through the use of downstream level-shifting devices such as dual-mode DP to HDMI™ adapters.
