FAQ:

Q: Where to buy the USB to RJ45 ethernet adapter for MacBook Air?

A: I bought my MacBook Air’s USB to RJ45 (Ethernet) adapter from DealExtreme – USB 2.0 10/100Mbps RJ45 LAN Ethernet Network Adapter Dongle for just $7.69 (including free shipping to anywhere in the world).

Q: What are the routing requirements for RJ-45 connectors?

A: The routing requirements between the PHY chip and RJ-45 connectors are much more strict. TX and RX lines are routed as differential pairs, and these traces must be length matched and symmetric. Remember that this circuit and associated traces are carrying analog signals, thus they need to be routed over an analog ground plane.

Q: What is the termination circuit between RJ45 and PHY?

A: There is also a specific termination circuit that must be placed between the PHY and the RJ-45 connector, commonly termed “magnetics” within the Ethernet layout routing standards. A magnetics termination circuit involves four transformers for a single RF-45 connector, two on each RX and TX differential pair.
