Diodes Incorporated recently released the automotive-compliant PI2DPT1021Q, a bit-level ReTimer designed to meet the signal integrity and reliability demands of next-generation vehicles, including electric vehicles (EVs).
The device supports both DisplayPort (DP) 1.4 and USB 3.2 standards for USB Type-C interfaces used in infotainment systems, digital instrument clusters, rear-seat displays, smart cockpits, and active cable assemblies.
The PI2DPT1021Q is a 10Gbps ReTimer capable of maintaining high-speed data transmission required by modern in-vehicle networks. It preserves signal integrity through receiver adaptive equalization, compensating for channel losses up to -23dB at 5GHz.
The device also integrates jitter cleaning and an adaptive continuous time linear equalizer (CTLE), along with selectable 3-tap transmitter adjustment for fine-tuning.
With flexible 4:4 channel operation, the ReTimer supports system-on-chip (SoC) devices featuring integrated USB/DP crossbar switches. Configuration via an I²C interface enables multiple modes, including four-lane DP 1.4 (HBR3), two-lane DP 1.4 (HBR3) with one-lane USB 3.2 Gen2, or two-lane USB 3.2 Gen2 operation.
The bi-directional architecture provides flexibility in signal flow direction—an advantage for active cable and modular EV designs, while ultra-low latency (below 1ns) ensures interoperability between various USB and DP components across the vehicle.
The PI2DPT1021Q supports USB and DisplayPort power management standards, including U0–U3 and D3 states, and includes automatic power-saving features for low-energy operation. It runs from a single 1.8V supply and operates across a wide temperature range (-40° to +105° C), making it suitable for harsh automotive and EV environments.
Packaged in a compact X1-QFN2845-32 (2.85 x 4.5, 0.4mm pitch), the PI2DPT1021Q is designed for space-constrained automotive PCBs. A standard compliance version, PI2DPT1021, is also available for industrial and commercial applications.
