Automotive Ethernet to RJ45 Adapter

[ethermike]

I've just received my OM14510-SJA1105TJP: Automotive Ethernet Switch Application Board. The 4 PHYs are Automotive Ethernet connections but I would like to interface via RJ45 for development purposes. I checked with NXP support and there's no adapter available for sale. What's the best/cheapest/fastest way to convert Automotive Ethernet to standard RJ45 ethernet?

The most cheapest option I could find was the DP83TC811EVM from TI for $300. Kind of disappointed there aren't more reasonable options to facilitate automotive Ethernet development.

You can refer to this:

I'm looking for a more economical option. My hope was that NXP sold something like this to support development.

You mean converter between 100Base-TX to 100Base-T1?

Yes I believe so. The evaluation board I mentioned has two wire screw clamps for Automotive Ethernet on each of the four ports:

I need to convert from the two line Automotive Ethernet to an RJ45 plug so I can use normal ethernet cables. I don't currently have any devices which use Automotive Ethernet.
