A new series of automotive-compatible PCI Express (PCIe) 3rd packet switches from chipmaker Diodes Inc. gives developers port configuration flexibility in automotive networking applications. Their architecture enables flexible port configuration with upstream, downstream, and cross-domain end-point (CDEP) ports being assigned according to requirements.

The PI7C9X3G606GPQ offers 6-port/6-lane operation, the PI7C9X3G808GPQ 8-port/8-lane, and the PI7C9X3G816GPQ 8-port/16-lane. The switches are targeted at ADAS, telematics, infotainment systems, and controllers that are utilized 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 <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, thereby simplifying designs, saving space, and reducing the associated component count. Their typical latency is only 150ns.

The ability to select between 6 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.

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. In 1,000 piece quantities, the PI7C9X3G606GPQ is available at $28, the PI7C9X3G808GPQ is available at $46, and the PI7C9X3G816GPQ is available at $74.
