Communication interfaces having reduced signal lines. In one aspect, a physical layer circuit, set forth by way of example and not limitation, interfaces a link controller and a device communication bus, and includes a wrapper coupled to a first interface bus having only six or less communication lines and coupled to a second interface bus having a larger number of communication lines than the first interface bus. The wrapper can communicate first signals with the link controller over the first interface bus and perform conversion between the first signals and second signals communicated on the second interface bus. A core, coupled to the wrapper by the second interface bus, can communicate device signals with the device communication bus by performing conversion between the second signals and the device signals. |
