PCIe packet switches are automotive-qualified for telematics and ADAS
The PI7C9X2G304EVQ and PI7C9X2G404EVQ PCIe 2.0 packet switches packet switches are automotive-compliant for use in telematics/ADAS, navigation systems, in-vehicle wireless routers, and emerging applications such as V2V and V2X communications. They offer three-ports/four-lanes and four-ports/four-lanes, respectively.
The switches are designed to increase the fan-out of PCIe ports on SoCs, ASSPs, microprocessors and FPGAs to support these advanced features in the automotive industry. Both the PI7C9X2G304EVQ and PI7C9X2G404EVQ are qualified to AEC-Q100 Grade 2, and have an operating temperature range of -40 to +105 degrees C. They are manufactured in IATF 16949-certified facilities.
Interoperability at the system level is guaranteed, confirms Diodes, through compliance with the PCI-SIG PCIe Rev 2.1 standard.
Advanced features include an integrated clock buffer and support for peer-to-peer traffic, delivering greater system performance. The low-power operation is complemented by link power management, including active-state power management L0 and L1, device-state power management D0, D3Hot and D3Cold. Power dissipation in L0 is 300mW (typical), dropping to 35mW in PCI-PM L1.1 D3Hot PM sub-state mode.
Latency for a packet running through the switch without blocking is 150nanoseconds, and latency tolerance reporting improves platform power management. While the default mode is cut-through, store and forward modes are also supported. Peer-to-peer traffic is enabled through access control service support.
