Retimer boosts USB 3.2 and DP in auto cockpits
A bit-level retimer from Diodes, the PI2DPT1021Q enables high-speed USB and DisplayPort (DP) connectivity in automotive smart cockpits and infotainment systems. The 10-Gbps bidirectional device supports USB 3.2 and DP 1.4 standards for various automotive USB Type-C applications.
The retimer has 4:4 channels, configurable via I²C for different modes: four-lane DP, two-lane DP with one-lane USB 3.2 Gen 2, or one- or two-lane USB 3.2 Gen 2. It is AEC-Q100 Grade 2 qualified and operates over a temperature range of -40° to +105 °C.
To maintain signal integrity, the PI2DPT1021Q offers receiver adaptive equalization that compensates for channel losses up to -23 dB at 5 GHz. It also provides low latency (<1 ns) from signal input to output, ensuring good interoperability between USB and DP devices. Additional features include jitter cleaning, an adaptive continuous-time linear equalizer (CTLE), and a 3-tap transmitter with selectable adjustment.
The PI2DPT1021Q retimer costs $1.65 each in lots of 5000 units.
