Automotive packet switches target applications in infotainment, telematics and ADAS

Diodes Incorporated has introduced the PI7C9X2G304SLQ and PI7C9X2G404SLQ representing the first-ever packet switches to be automotive-qualified to AEC-Q100 grade 3. These PCIe 3-Port/4-Lane and 4-Port/4-Lane packet switches are specifically designed to meet automotive industry requirements, targeting applications in infotainment, telematics and ADAS. These parts feature advanced power management, hot-plug connectivity and an integrated 100MHz clock buffer to ease design and lower BOM cost. Vehicle telematics and infotainment systems demand connectivity that meets both the latest communication standards and automotive reliability criteria. Based on their industry-leading PI7C9X2G PCIe2 Packet Switch family, the PI7C9X2G304SLQ and PI7C9X2G404SLQ devices offer compliance with AEC-Q100 Grade 3 over the full automotive temperature range of -40C to +85C, while meeting PCISIG PCIe rev. 2.1 to assure good interoperability. With an MTBF rate of over 50 million hours, these highly reliable automotive devices are characterized by low power dissipation - typically 650mW in normal L0 mode and just 200mW in L1 mode - which eases thermal design. High performance is also ensured by the family’s low latency, which is typically 150ns for a packet running through the switch without blocking. To meet non-automotive requirements for greater fan-out, port-extension flexibility, and to support multiple-host functionality for failover operation, Diodes has also introduced 9-port/12-lane and 16-port/16-lane versions of its PCIe packet switches. These support multiple x2 downstream ports, making them well-suited for a wide range of embedded system, networking, telecom and storage applications, such as backplanes, industrial process controllers, switches, routers, gateways, base stations, RAID controllers, solid state drives, and NAS equipment.
