“The architecture used enables flexible port configuration with upstream, downstream and CDEP [cross-domain end-point] ports being assigned according to requirements,” according to the company. “They can connect with up to seven different endpoints and support multi-host applications.”

PI7C9X3G606GPQ offers 6-port/6-lane operation, PI7C9X3G808GPQ 8-port/8-lane and PI7C9X3G816GPQ 8-port/16-lane.

On board, long tracks with losses of <30dB can be supported, and each switch has a built-in clock buffer. Typical latency is 150ns.

 

All three ICs are AEC-Q100 Grade 3 qualified, manufactured in IATF 16949 certified facilities, and support PPAP documentation.

Packaging options include 144pad FCCSP, 196pad HFCBGA and 324pad HFCBGA packages.

The switches are aimed at driver assistance, telematics, infotainment systems and zonal networking controllers.

PI7C9X3G808GPQ has been used to aggregate dual automotive processors in an automotive processing reference design, which will be on show at the PCI-SIG Developers Conference in Santa Clara – stand 18.
