Aitech C695

Supports up to 24 PCIe Ports, Conduction and Air-Cooled Versions

Manufacturer: Aitech
Aitech C695

Aitech’s C695 is a high-performance 3U VPX PCI Express Switch for embedded and harsh environment applications. PCIe switching is performed by the IDT 89H32NT24AG2 32-lane/24-port Gen2 PCIe switch, which provides powerful switching capabilities and integrated DMA engines for fast data transfers.

Up to eight PCIe x4 ports are routed from the IDT switch to the C695 VPX backplane connectors. When the C695 is equipped with the optional XMC site, eight of the IDT switch PCIe lanes are routed to the XMC and XMC I/O is routed to the VPX backplane connectors.

Additional backplane PCIe port/lane grouping options are user-configurable via the onboard EEPROM. User configuration options also include Transparent and Non-Transparent (NT) ports and upstream/downstream port configuration


FeaturesPCIe Switch Features:
• Supports Gen2 (5 GT/s) and Gen1 (2.5 GT/s) speeds
• User configurable via on-board EEPROM device (1)
• Low latency cut-through architecture
• Automatic per port link width negotiation
• Supports 128 Bytes to 2 kB maximum payload size
• Supports up to 8 independent switch partitions
• Transparent / Non-Transparent (NT) port configuration (up to 8 ports configurable as NT)
• Upstream / Downstream port configuration
• DMA support
• Multicast support
• Port Status Indicator LEDs
Variant 1: PCIe Eight x4 Backplane Ports, no XMC I/O
Variant 2:
• Six x4 Backplane Ports (3) + One x8 Port at XMC Site
• XMC I/O: 20 Differential Pairs + 2 Single-Ended
