The DIODES Advantage

Automotive-compliant 13.5Gbps USB Type-C USB 3.2/DP 2.1

UHRB13.5 6:4 active crossbar mux for routing/multiplexing

USB-C and/or DP signals.

The PI3DPX1235Q is a DisplayPort (DP)

2.1 UHBR13.5/USB 3.2 Gen 2, 6:4 active

mux linear ReDriver with data rates up to

13.5Gbps for USB Type-C automotive

applications. It is compliant to the VESA DP

Alt 2.1 UHBR13.5 and USB 3.2 Gen 2

industry standard.

It multiplexes either just one lane of USB

3.2, one lane of USB 3.2 and two channels

of DP 2.1 UHBR13.5, or four channels of DP

2.1 UHBR13.5 to the USB Type-C

connector. In addition, the AUX± channels

are also multiplexed to the USB Type-C

connector.

The DP 2.1 and USB 3.2 Gen 2 signals’

signal integrity can be easily adjusted using

I2C control to amend the equalization,

output swing linearity, and flat gain values.

This allows the DP/USB 10Gbps signal

performance to be optimized over a wide

variety of physical media by reducing inter-

symbol interference jitters.

Non-blocking linear equalization does not

block the receiver DFE’s adaptive channel

controls, enabling support of DisplayPort

Transparent Link Training (LT) without

dependency of the DP-Aux channels

listener.

It is available in the 40-pin W-QFN6040-40

(ZLB40) with a 4mm x 6mm footprint.

UHBR13.5 6:4 Active-Crossbar Mux Improves Interconnectivity in
