Looking for PCIe packet switch

[fchk]

Hello world;

I'm looking for a suitable PCIe packet switch with these features:

• PCIe Gen3 preferred, PCIe Gen2 minimum
• Upstream interface: 1/2/4 lanes
• Downstream interfaces: 2 or 3 single lane
• preferred: Refclk buffers integrated
• preferred: QFN package with less then 128 pins
• parts and datasheets available in Europe
• low quantities (tens or hundreds)

The Diodes/Pericom parts available on Digikey and Mouser are Gen2 only.
Any sources for Asmedia?

Any other suggestions?
