Diodes, Inc has introduced the PI7C9X2G304SLQ and PI7C9X2G404SLQ, the first packet switches to be automotive-qualified to AEC-Q100 Grade 3.

The PI7C9X2G304SLQ is a PCI Express® three port/four lane packet switch, and the PI7C9X2G404SLQ is a four port/four lane device. Featuring advanced power management, hot-plug connectivity and an integrated 100MHz clock buffer to ease design and lower bill-of-materials cost, these parts are ideally suited to use in data-rich in-car features such as infotainment systems.

Based on Diodes’ PI7C9X2G PCIe® 2 packet switch family, the PI7C9X2G304SLQ and PI7C9X2G404SLQ devices comply with the AEC-Q100 Grade 3 specifications over the full automotive temperature range of -40°C to 85°C, while meeting the requirements of the PCIe v2.1 standard to assure good interoperability with other PCIe devices.

Highly reliable, the new Diodes packet switches offer a mean time before failure of more than 50 million hours. In addition, their low power dissipation makes for easier 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.

Diodes’ automotive-grade PI7C9X2G304SLQ and PI7C9X2G404SLQ packet switches are offered in a 14mm x 14mm, 128-pin LQFP package.

Diodes has also introduced 9 port/12 lane and 16 port/16 lane versions of its PCIe packet switches, the PI7C9X2G912GP and PI7C9X2G1616PR, for use in non-automotive systems.
