New Product

The automotive compliant* PI2DPT1021Q is

a bit-level retimer providing receiver

adaptive equalization, compensating

channel losses up to -23dB at 5GHz signals.

The device, with its 10Gbps data handling,

supports DisplayPort (DP) 1.4 and USB

3.2 standards for automotive USB Type-C®

applications such as rear seat entertainment

and active cables.

The PI2DPT1021Q has 4:4 channels,

supporting system-on-chip (SOC) devices

with an integrated USB/DP crossbar switch

with I2C. The I2C is used to select:

▪

Four-lane DP

▪

Two-lane DP and one-lane USB 3.2

Gen2

▪

One- or two-lane USB 3.2 Gen2

The PI2DPT1021Q complies with USB

power management states for active mode

(U0) and power-saving modes (U1, U2, U3).

The bi-directional design provides flexibility

when the DFP and UFP signal flows are

swapped, which supports active cable

applications and signal flow selection.

Diodes also provides the PI2DPT1021

commercial-grade device for industrial

applications

The PI2DPT1021Q is packaged in the very

small X1-QFN2845-32 (0.4 mm pitch)

package, supports AEC-Q100 Grade 2, and

operates across the -40

C to +105C

temperature range.

*Automotive-compliant - AEC qualified, manufactured in

sites certified to IATF 16949 supporting PPAP

documents.
