Diodes expands data lane versatility with PCIe 3.0 packet switches
At the PCI-SIG Developers Conference, Diodes introduced a series of automotive compliant PCI Express (PCIe) 3.0 technology packet switches for next generation in-vehicle networking applications.
The architecture enables flexible port configuration with upstream, downstream, and cross-domain end-point (CDEP) ports being assigned according to requirements.
The PI7C9X3G606GPQ offers six-port / six-lane operation, the PI7C9X3G808GPQ eight-port / eight-lane and the PI7C9X3G816GPQ eight-port / 16-lane. The switches are targeted at advanced driver assistance systems (ADAS), telematics, infotainment systems and controllers that are used as zonal networking architectures continue to emerge.
The elevated signal integrity performance provided by these PCIe packet switches support long trace lengths, with losses of less than 30dB. They can connect with up to seven different endpoints and support multi-host applications. Each switch features a built-in low-power clock buffer, simplifying designs, saving space, and reducing the associated component count. Their typical latency is only 150ns.
The ability to select between six and 16 lanes gives engineers using these new packet switches broad flexibility to develop projects quickly, and with the most suitable options. Advanced power management functions ensure constant energy-efficient operation, added Diodes.
The PI7C9X3G606GPQ, PI7C9X3G808GPQ and PI7C9X3G816GPQ are all AEC-Q100 Grade 3 qualified, manufactured in IATF 16949 certified facilities, and support PPAP documentation. They are supplied in 144-pin FCCSP, 196-pin HFCBGA, and 324-pin HFCBGA packages.
The PI7C9X3G808GPQ has been successfully used to aggregate dual automotive processors in an automotive processing reference design.
