A new series of automotive-compliant PCI Express (PCIe) 3.0 technology packet switches for next-generation, in-vehicle networking applications has been unveiled by Diodes Incorporated (Diodes) at the PCI-SIG Developers Conference in Santa Clara, California.
The devices feature an architecture which enables flexible port configuration with upstream, downstream and cross-domain end-point (CDEP) ports being assigned according to requirements.
Diodes latest offering consists of the PI7C9X3G606GPQ for 6-port/6-lane operation, the PI7C9X3G808GPQ for 8-port/8-lane, and the PI7C9X3G816GPQ for 8-port/16-lane. The switches are designed for use within ADAS, telematics, infotainment systems and controllers used as zonal networking architectures.
Additional benefits of the PCIe packet switches include support for long trace lengths – with losses of <30dB – and the ability to connect with up to seven different endpoints. The components also support multi-host applications. Each switch has also been designed with a built-in low-power clock buffer to save space and to reduce the associated component count.
The PI7C9X3G606GPQ, PI7C9X3G808GPQ and PI7C9X3G816GPQ are all AEC-Q100 Grade 3 qualified and manufactured in IATF 16949-certified facilities. They support PPAP documentation and are supplied in 144-pin FCCSP, 196-pin HFCBGA, and 324-pin HFCBGA packages. Additionally, the PI7C9X3G808GPQ has been used to aggregate dual automotive processors in an automotive processing reference design.
“Diodes Incorporated’s contributions to developing the PCIe specification-based products continuously bring new benefits to automotive and other markets, thus growing the PCIe ecosystem,” said Al Yanes, president and chairperson, PCI-SIG.
“The flexibility of these PCIe packet switches offers many advantages for automotive applications,” added Dr Jin Zhao, senior vice president, Analog Business Group, Diodes Incorporated. “This new series of automotive-compliant PCIe packet switches is designed to expand PCIe signal outreach in next-generation vehicle interconnections.”
