2024-05-02 | Return

Diodes Incorporated (Diodes) brings extra convenience and performance to state-of-the-art in-car connectivity with the introduction of its 10Gbps automotive-compliant* crossbar switch. Designed for routing USB 3.2 and DisplayPort™ 2.1 signals through a USB Type-C® connector, Diodes’ new switch, the PI3USB31532Q, ensures high signal integrity and saves power compared to a conventional crossbar multiplexer and ReDriver™. This crossbar switch is targeted for use in rear-seat entertainment systems and smart cockpits with their large, high-definition displays.

The PI3USB31532Q supports three configuration modes with USB Type-C compliance, providing a range of options for designers. It can connect a single lane of USB 3.2 Gen 2 to the USB Type-C connector; connect one lane of USB 3.2 Gen 2 and two channels of DP 2.1 UHBR10; or connect four channels of DP 2.1 UHBR10. When configured for DisplayPort, the PI3USB31532Q also connects the complementary AUX channels to the USB Type-C sideband pins: SBU1 and SBU2. Its configuration is controlled by I2C or on-chip logic using four external pins.

Packaged in the 40-pin W-QFN3060-40 and occupying only 3mm x 6mm, the PI3USB31532Q delivers flexibility and performance with the advantage of a space-saving outline. High signal integrity is assured with its -3dB bandwidth of 8.3GHz, and low insertion loss, return loss, and crosstalk of -1.7dB, -15dB, and -38dB respectively at 10Gbps.

The new crossbar switch is automotive compliant*—qualified to AEC-Q100 Grade 2, allowing use in environments exposed to temperatures from -40°C to +105°C, manufactured in IATF 16949 certified facilities, and is PPAP capable. The PI3USB31532Q is available at $1.10 in 3,500-piece quantities.
