[May 21, 2024, Plano, Texas, USA] Diodes Incorporated (Diodes) has launched a 10Gbps automotive-compliant crossbar switch, bringing more convenience and performance to advanced in-car connectivity features. Diodes' new switch PI3USB31532Q is designed to enable USB 3.2 and DisplayPort™ 2.1 signal routing through the USB Type-C® connector, ensuring high signal integrity and saving more power than traditional crossbar multiplexers and ReDriver™ signal conditioners. This crossbar switch is suitable for automotive rear-seat entertainment systems and smart cockpits equipped with large, high-resolution displays.
The PI3USB31532Q supports three USB Type-C compliant configuration modes, providing designers with multiple options. It can connect a single USB 3.2 Gen 2 channel to a USB Type-C connector; connect a single USB 3.2 Gen 2 channel to a dual DP 2.1 UHBR10 channel; or connect a quad DP 2.1 UHBR10 channel. When configured for DisplayPort, the PI3USB31532Q also connects the complementary AUX channel to the USB Type-C sideband pins: SBU1 and SBU2. The device's configuration mode is controlled by I2C or on-chip logic using four external pins.
The PI3USB31532Q is available in a 40-pin W-QFN3060-40 package with an area of only 3mm x 6mm, which enables design flexibility and high performance with the advantage of space saving. The bandwidth is -3dB at 8.3GHz, and the insertion loss, return loss and crosstalk are as low as -1.7dB, -15dB and -38dB at 10Gbps, respectively, which ensure high signal integrity.
The new crossbar is automotive-qualified* - it is AEC-Q100 Grade 2 qualified, can be used in -40°C to +105°C ambient environments, is manufactured in an IATF 16949 certified facility, and supports PPAP. The PI3USB31532Q is available in 3,500-unit quantities.
